I'm trying to append an object from another file. Unfortunately Blender crashes immediately. The problem seems to be linked to materials that have an RGB image node in them. An object with such a material crashed Blender when appending. Appending just the material works. But as soon as I assign that material to an object in the scene, Blender crashes as well.

It seems that another user had a similar issue in another post from back in February/March ... viewtopic.php?f=114&t=81239&p=422720&hi ... nd#p422720

Latest version (27.15), Windows 10 64-Bit, RTX3060.

Any ideas what the reason can be?

[EDIT] I also tried to append a "World" setup that has HDRI maps in it. Same issue. Blender crashes immediately.

I've attached the crash log. Maybe it helps.

I've tried appending world node (hdri) and material with image nodes and Blender didn't crash.

Did you use the latest version - 27.15? On Windows 10?

Yes, 27.15

Those are the most annoying bugs to find. I'll do my best to narrow down the issue. But maybe the devs could check my crash log above to get some ideas about what's going on. I'm not the only one with that issue. And that's pretty much a show stopper unless I can find a fix.

I did a few more tests. Removed all the presets and third party addons from Blender. But there's no way I can get it to work. Blender always crashes. I've also did a test on my second PC (similar system but uses a GTX 780Ti) and the crashes also happen there.

I've created a test file. Please try to append the "Cube" object from there. After that start the Render Preview (IPR). At that point Blender crashes on my PC.

As I've read in some other forum that the Ryzen CPU might be an issue, I should mention that I use a Ryzen 7 3700X. So maybe another Ryzen user could cross-check the issue. Unfortunately I don't have an Intel PC nearby.

I found a way how to prevent the crashes. It's not very convenient though.

If I create a new RGB image node in the Shader editor, I can append objects afterwards (as many as I want). It has to be an RGB image node. For example an new RGB color node still results in crashes. So this probably has to do with the RGB image nodes and their initialization.

We'll check this, thanks!

Tried here with the latest version (27.16) and I got no crash, so this has very likely been fixed already.

Great. I'll check it once the new version is available.

However it would be great if you could check if the problem is there in 27.15. There was a user above who had no issues with that. So it might already work in 27.15 for you as well. In that case, it might not have been fixed.
