I've read plenty of discussions about the differences between OpenGL vs. DirectX Normal Format.

I was troubleshooting some materials that I thought I had exported correctly for the renderer I'm using (which requires OpenGL format).
For all of my materials, I had set the Project to use OpenGL format, set all materials' 'Normal Format' dropdown under 'Technical Parameters' to OpenGL, and made sure that the exported format was also using OpenGL.

Everything seemed fine for just about all the materials.

However, I began to notice that some of the materials were exhibiting a 'flipped Y' behavior when lights were shining on them from above or below.

It turns out that for those troublesome materials, the 'Normal Format' had no effect. Digging a little deeper, I came to discover that their normal information is coming from their Height channel.

So the question:  How can I easily set these to export correctly without having to manually switch the exporter every time?

One of the materials in question (from Substance Source): https://source.substance3d.com/allassets/bfdc10fea395831c59deb9388cd6bbdafcd02d20?q=ceramic%20enamel

Note that changing 'Normal Format' under the Technical Parameters has no effect for this one ^

When my layout is set to 3d/2d view split, and then I press c to switch to see a different channel, the 2d view draws at a lower resolution. It remains at a lower resolution until my cursor rolls over the 2d view, at which time the resolution corrects itself.

This wouldn't be a huge deal except that I'm often not hovering over the 2d view when I'm working, say, in the Layer editor.

Apologies for the tiny GIF, but you can still see what's happening, particularly when I switch to 'Emissive' mode (the mostly black image). You can see the edge of the one square looking really blurry at first:

NOTE:  This occurs in any project, regardless of what resolution I'm currently set to.

When selecting a folder in the Layer panel and choosing 'Create Smart Material', the whole app crashes every time. It appears that the crash occurs when the thumbnails are being generated. When I restart Painter, everything is fine until I click on Smart Materials-- as it's generating the thumbnails again, it crashes every time.

I'm positive this is the culprit-- When I rename the Smart Material starting with a letter that's further down the alphabet so the item appears later in the list, Painter doesn't crash on start. Only when I scroll far enough to see it does it crash.

Having a hard time grabbing a screenshot because the cursor(s) and other UI go away, but when I use the Eyedropper tool next to a BaseColor parameter and drag it onto the 3d or 2d view, the existing paintbrush tool 'blocks' the eyedropper from selecting the proper color. Instead, the eyedropper grabs the tinted color where the paintbrush cursor covers.
It may occur with other eyedroppers other than just BaseColor...

I'm using:  Painter v.2018.2.3

This only started happening mid-session. Going to try to restart...

I'm getting a whole lot of errors in my log file as I work. I'm not sure if they're contributing to another bug I'm experiencing where I can't save without crashing, but regardless, I get a ton of these:

I know they're just WARNINGS, but I'm guessing that it can't be helping anything since they're spamming the log so often.

I'm running version 2018.2.3

I'm not 100% clear on how the 3d camera (orbit) works in Painter, but it seems to have been built for models where you are on the exterior. As soon as I try to work with a model that is more of an architectural interior, the camera seems to behave strangely.
It becomes difficult to zoom in far enough to reach the interior of the model, almost as if the camera has some sort of surface detection where it thinks it's colliding with the surfaces, or perhaps it's rotation pivot collides with surfaces. Once I get the camera inside the model, I can dolly the camera in faster than when I was 'stuck' outside. But to reach the interior, I have to dolly in (either via mouse wheel or alt+rmb) at a much higher rate, which is a carpal tunnel nightmare.
It could also be that the camera behaves differently as it approaches the scene origin and slows down as it gets there. Hard to tell without knowing how it was designed.

Whatever the reason, it would be nice to have the option to change the way the camera behaves, similarly to how Maya handles it.

Substance PainterSubstance Painter - Feature Requests - VR camera support
 on: August 08, 2018, 10:37:09 pm 
I'm currently working on several VR projects and have come to discover just how slow the iteration loop can be for seeing the materials/textures in a head-mounted display. Since Allegorithmic is already ahead of the curve when it comes to glTF support (https://www.khronos.org/gltf/), it seems natural that they'd also embrace cutting-edge display technology.

So much is gained from actually seeing substances stereoscopically-- things like gamma, normal maps, and mipmapping can often appear slightly differently in VR. Being able to iterate within Designer or Painter before exporting everything is essential for smooth production.
