How to run DAZ Studio on a remote machine via RDP

by

I’ve been playing with Windows Azure the other day, specifically to hire rendering machines. My idea was very simple: if I have a long animation to render, why not pay a nominal amount of cash, but have the result back within hours rather than days?

So I created a Windows VM, logged in from my Mac via RDP (Remote Desktop Connection), installed DAZ Studio and some content… but sadly I couldn’t start DAZ Studio. I remember having had this problem before on my home network, where I have a similar setup.

This happens because DAZ Studio needs OpenGL 1.3 or higher, and with an RDP connection, only OpenGL 1.1 is supported. Quite rightly so, DAZ Studio throws an error message and quits. However, the app works just fine via RDP, so how can we circumvent it closing prematurely?

What is the /data/auto_adapted folder in DAZ Studio

by

I was setting up an animation on one system, then transferred the scene over to a more powerful rendering machine. Usually DAZ Studio 4.9 does a good job at installing required content automatically (thanks to DAZ Connect), but this time my scene showed up with several scary grey blocks instead of content. In addition, I …

Getting started with ShadowBox in ZBrush

by

ShadowBox is an interesting feature with which we can create 3D geometry from three intersecting masks. Let’s see how to get started with it step by step in ZBrush 4R7. Select any tool to begin, perhaps something that can serve as a starting point. I’ll use the Dog tool. To do this, hit the COMMA key …

How to download previous versions of Marvelous Designer

by

Marvelous Designer (or Marvy D as some fans call it) receives frequent updates with a plethora of new features. With every round new version number, and upgrade fee is necessary – if you bought the software with a perpetual license (like I have, because I genuinely dislike the subscription model… but I digress).

This means that it is very likely that a new version passes you by, and you have the need to download an older version of Marvelous Designer.

Good thing you can: from the Download Archive.

How to play HALO on Windows 10

by

The other day I bought a brand new copy of the 2001 classic HALO – Combat Evolved for Windows. I really liked this game and played it on the original XBOX quite a bit – even thought I must admit that I neither liked nor got it the first few times I picked it up. …

How to avoid missing textures in Reality for DAZ Studio

by

I was playing around with Reality for DAZ Studio the other day, and the above phenomenon occurred. It’s a Michael 6 render that should have worked out of the box – especially because Reality is clever enough to convert his skin shaders to automatically. The render worked fine on one of my machines, but not on another.

Strangely enough though, I could see the textures fine in the viewport. And a quick test render in both 3Delight and Iray showed the textures fine too. But Reality and LuxRender wanted to render the skin tone as some scary metal.

So what’s going on?

The culprit is DAZ Connect. On this second machine, Michael 6 was installed not via the DAZ Install Manager, but from within DAZ Studio via DAZ Connect. This has happened because I loaded the scene (from Dropbox), and DAZ Studio recognised that Michael 6 was not installed, and hence offered to install him for me. I accepted the generous offer, but Reality and LuxRender can’t handle textures installed via DAZ Connect.

How to render “Manuel Bastioni LAB” characters without purple skin in Blender

by

I recently discovered the Manuel Bastioni LAB add-on for Blender. Judging it only by the title you’d never guess it’s an extravagant people generator of the highest caliber! Bastioni was working with the folks from MakeHuman for many years, but The LAB is his own project.

In a nutshell, it creates ready-to-use characters, complete with poses and morphs, as well as many other complex goodies. And as with many complex things, rendering can take a while. I tend to prepare a scene on one machine, transfer it to a faster system and let it render while I setup the next scene.

This workflow usually works a treat with .blend files, but not necessarily with those containing Manuel Bastioni characters. Turns out the skin has a good chance of looking alien purple. Quite a nice effect, but perhaps not all the time.

Lucky for us, knowing why this happens will help us understand how to fix the problem. It’s not a bug, just a question of which box to tick when saving those files. Let me show you which box that is and how to avoid the purple skin effect.

How to use Spotlights with NVIDIA Iray in DAZ Studio

by

The NVIDIA Iray render engine can be a bit of a mysterious box sometimes. Especially when it comes to lighting. But it doesn’t have to be. Let’s see how we can add a standard spotlight to our scene and set it up so we can use it properly with Iray.

Let’s take this simple scene as as demo and a staring point. It’s a there and a plane, both of which have Iray shaders applied (it’s Walnut on the floor, and orange car paint on the sphere).

Iray Default Light (IBL)

1-iray-default-lights

The default lighting for a new DAZ Studio Iray scene comes with a small HDRI image applied by default, and when we render our scene, we can see the effects of that light source.

Notice that there’s a small specular highlight on the sphere, on the left hand side (a small shots spot). This is the sun’s hotspot from the HDRI image map. As you turn the camera around, the hotspot moves. Alternatively you can move the Iray Dome to move that hotspot (under Render Settings – Environment – Dome – Dome Rotation).

Not every HDRI image has a sun though, and depending on which map you use, you may not even see such a hotspot in your renders.

Adding a Spotlight

The left hand side of our sphere is a little darker, and if this was a character’s face, we may want to brighten it up a bit. In 3Delight we’d just add a standard spotlight, tweak the intensity and shadows until we’re happy, and then we’re done with it. With Iray we’ll do the same thing – but the settings are just a little different.

Combining a DAZ Studio Render and a background image in Photoshop

by

In this episode I’ll show you how to render an image in DAZ Studio and compose it onto a background image in Photoshop. We’ll use the Shader Mixer and a Shadow Catcher to make the figure cast a shadow but be otherwise transparent in DAZ Studio. In Photoshop we’ll add artificial depth of field to …

How to create a translucent shader in Blender (Cycles)

by

By default all our 3D objects are opaque, meaning light does not pass through them. Like a brick wall. But many objects in reality let some amount of light through, like a piece of paper or a glass of lemonade. This partial transparency is called translucency. In the picture above, light passes through the leaf, …

How to create a transparency shader in Blender (Cycles)

by

screen-shot-2016-11-21-at-14-03-09

Texture files can have a transparency value, and as such we’d like to use it on occasion with 3D objects. The above image is created using flat square leaves, onto which an image of a leaf is projected. Outside the leaf, the area on the PNG file is transparent.

Here’s how to create a Cycles Shader in Blender that will show only the leaf and not the surrounding area of the texture.

How to make a texture repeat in Blender (Cycles)

by

Sometimes we need a seamless texture to repeat on an object without the help of Photoshop. That’s possible in Blender’s Node Editor, albeit not exactly intuitive. We need to add both a Texture Coordinate node, as well as a Mapping node to our shader to make this happen. Here’s how to do it: setup your texture …

How to grow grass on a landscape in Blender

by

I have previously grown some grass on a terrain in Carrara, and thought I’d try the same in Blender. I didn’t know much about how to do this, but the approach is very similar in Blender.

Like with my Carrara approach, I’ve modelled a few grass stalks from a cylinder first. Those are then replicated over a larger terrain. Neither a replicator nor a terrain generator exists in Blender, so here’s how I did it.

How to flip or rotate a texture in Blender

by

When you’re UV unwrapping in Blender, it can sometimes happen that a texture doesn’t show the way you had intended it to. Instead it may appear rotated or mirrored (flipped). Take the above example of a simple frame with a picture in the middle. When I originally added the texture file after unwrapping, the crab …

How to rename Parameter Dials in DAZ Studio

by

screen-shot-2016-11-17-at-18-22-57

Parameter Dials are everywhere in DAZ Studio. But sometimes they’re not in the right place, or they’re not called what we’d like them to be called. For example, if you bring in a Morph Target via Morph Loader, DAZ Studio will create a folder by that same name.

It’s easy to change most Parameter Dials. Here’s how to do it.

How to add margins between UV islands in Blender

by

When UV islands are packed too tightly together, there’s little to no room between them. That’s great because it makes use of every available pixel on the UV Map, however when it comes to texturing in Photoshop, selecting separate islands is very difficult. Blender has a nice feature that lets us add a margin in …

How to turn a mesh into a path in Blender

by

Not all 2D shapes are created equal in Blender: create a circle via Add – Mesh – Circle and it will be fundamentally different to creating one with Add – Curve – Circle. Even though, they look exactly the same in the viewport. The trouble begins when you want to do path related things on 2D …
