I'll look into it. There's been some complaints about rendering glitching out and I'm not sure what's causing it. I had some issues a while back but I wasn't able to replicate them

If you have anything like lua errors/"how to replicate", that would be helpful, perhaps a screenshot of the editor settings, color of the entity, etc... although that looks more like the image failed to load for some reason

I enabled transparent option. but when I am holding physgun or camera at the image, The render starts to ♥♥♥♥ it up.

Issue is pretty much not reproducible on my end. I've pushed a change that might help with the problem, but unless I have more information or encounter it myself, there's sadly nothing I can do. I'll be trying a few shots in the dark to fix the issue but no guarantees. Just did one a few days ago if you want to see if it's fixed now

Should now be fixed @Woody

I tested it out with duplicator but it made errors.
