bitmaps not showing

[Rhodesy]

Ive really struggled to get bitmaps to show consistantly in Max 2024 and corona 10. Some of them work but some dont, even when toggling the show bitmap button on the slate editor ribbon. I've tried different display modes like high quality but that makes no difference. Its a corona issue because if I recreate the same material with a standard max material with the same bitmap and real world scale settings it shows up fine but switching back to the corona material they disappear again. Its the same whether I use a max bitmap shader or the corona bitmap. Any ideas? Seemed better in Max 2023 and I seem to remember reeading the release notes that there were some 'improvements' to the corona bitmap display in R10 but thats not been my experience.

Slate material editor's toolbar button Show shaded material in viewport is broken in 3ds Max 2024. It's Autodesk's bug, not Corona's. You can use right-click menu in slate editor, or viewport configuration menu to show/hide materials preview, but slate editor's toolbar button will do nothing until Autodesk will fix it.

Ah great. I can get it to work with the right clicking in the slate editor like you said thanks. It was the fact I could get it to show with the Max material but not the corona one that had me thinking it was corona related. Hopefully they will sort that soon.

I"m surprised to hear that you got it working with standard material - for me that button is not working with any material and any active renderer.

[Rhodesy]

To be fair it just worked without pressing the button, so it might not be a direct comparisson.

Ive got a script you might find useful, I originally made it for vray but I just updated it for Corona. Not sure if its exactly what you are looking for but this is what it does:

Basically you can select a bunch of objects and press the button, it will find all the diffuse textures and show them in viewport. If it has opacity it will show the material instead (so you can see through the opacity in viewport). You might find it useful, often I have lots of objects that are just grey or whatever and just want to see all the diffuse textures immediately. Should work for both Physical/Legacy, CoronaBitmap and Bitmap.

Attached script.

Wow thanks James, sounds like a useful one. I've just downloaded.

No worries Rhodesy, just let me know if it does something funky.
