Bug-Report? Multi-Shader-Setup Rendering

[dapa5900]

Hi @OmarEmaraDev

I tried to create an Animation Nodes driven Multi-Shader-Setup for a Book generator I'm working on. I used an image sequence texture for that and drive the frame offset via the AN Material Attribute Output Node for the instanced materials.

It seems to work as intended rendering with Cycles in the viewport but when I want to render an image, Blender crashes every time. With Eevee it doesn't seem to work at all. I get some weird ghosting and sometimes the selected pages change. Sometimes I get the purple missing texture color and for the most part I can only see one of the page textures on all pages.

You can check the file here:

It's a bit messy but I highlighted all the material related nodes with a blue color. I actually packed all the textures into the file but I'm not sure if that worked correctly, as the blend-file size doesn't differ from the non-packed version so I also put the texture folder next to the project.

When you have time, it would be great if you could check this out. Thank you! :-)

@dapa5900 Hi. In the Material Instancer node you need to keep off the option Instance Material after instancing the material. You may also look into this answer on BSE: https://blender.stackexchange.com/questions/153377/in-animation-nodes-is-it-possible-to-make-a-node-to-translate-position-of-the-u/153499#153499

@dapa5900 What do you think about something like this?

@OmarEmaraDev

Thank you for setting this up so quickly, it already looks really fantastic.

Here's an image with my feedback so far on this:

As said, the option to wire in eg. RGB-values (for example if you want to crate a color palette) or procedural noises from the shader graph via sockets would be nice to have and could maybe also implemented later on if possible. But I think for now this looks awesome and should be sufficient the implement the basic functionality how to assign these values to instances then for example.

@dapa5900 The circle does nothing, I just needed a way to indicate which image is selected, not sure if there is a better way to indicate that. Clicking the dot will just select the image. The Remove button doesn't remove from bottom to top, it removes the selected item indicated by the dot.

For having RGB sockets, I am not sure how feasible this is yet. I will look into it later. I will try to publish a working prototype soon so that you can test it.

@great! Looking forward to test it.

@dapa5900 Here is an initial version for testing, feel free to open an issue there for feedback.
