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.

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 …

How to split and detach viewports in Blender

by

By default Blender has one window with multiple interface sections: the main viewport, the properties panel, the outliner, and so forth. We can easily create more of those sections by clicking on the little triangle in the top left corner of a window and drag left or down. Likewise, we can collapse those windows by …

How to upgrade Blender while retaining your settings

by

In this episode I’ll show you how to upgrade to a new version of Blender and copy your settings from a previous version. Blender is a bit “special” in that it does not automatically overwrite an existing version, instead it installs the new version alongside the old version. The idea is that if the new …

How to copy and paste materials in Blender

by

chocolates-gpu-render-37mins

Sometimes you want to use the same material on another object and only make a small change to it. Rather than this change affecting all linked objects, we need a new material with all the settings of the old material.

For example, in the above image I’ve used three chocolate shaders. They were all the same, except for the colour of the chocolate. I started with milk chocolate, then changed the colour for the dark and white chocolates.

There is an easy way to do this in Blender, albeit not entirely obvious at first sight. Let me show you how to copy and paste materials in this article.

How to render the current viewport in Blender 2.79

by

In other 3D applications, it is common to “look through” a camera to position and manipulate it with the usual viewport controls, and then render the result. In Blender things are a little different (of course). We can manipulate the viewport, but we cannot render it. We can see it rendered as a preview, by …

How to expand selections in Hexagon

by

I’ve just learnt of a new way to expand selections in Hexagon: select some faces (or edges), then position your cursor away from the object, then hold down CMD (Mac) or CTRL (PC) and drag in any direction. The selection will grow into the direction that you drag. It doesn’t always reliably work, because some weird …
