I’ve stumbled across something that I can’t explain to myself. Have a look at the GIF below.
I imported an OBJ and would like to render only the points. It looks fine from afar, but as soon as I zoom in, the mesh disappears.
This does not happen when I render only the lines or when I render it as a solid.
Does anybody know what might be causing this?
Ok, I found the solution. I uploaded a screenshot of the patch to ChatGPT and it immediately spotted the issue — even without me explaining the problem. I have to admit I was impressed.
Anyway, the actual solution is that a DynamicMesh needs a bounding box.
Without defining bounds, I was getting these kinds of rendering artifacts.
And this is how it looks now:
It goes without saying that ChatGPT also had an opinion about this workflow — according to it, rendering meshes as points like this is somewhat unstable and I’d be better off rendering small spheres instead.
Ah well… opinionated chatbots…
Make sure to put that in the cache region. In your screenshot, the bounding box gets calculated every frame for a static geometry.
@vincent.now Kind of crazy that GPT solved it looking at your screenshot only! Anyway thanks for bringing this up, had a similar issue and had no idea whats wrong. In my case it was a NullMesh that needed a bounding box to work properly.
Yes, I think so too!
