So, some time ago we ported PBR (from jme repository) in our project, but there we faced with not cool problem:
HDR images show dotted artefacts as you can see here:
This problem occur in some HDRI-s, but some work pretty stable (it is 2 different HDRI shot in same place with same camera in different light conditions):
This one is really fancy:
I am intended to make my own HDRI in blender (particularly), but HDRI from blender in jme looks really unstable. I dont know what occure this problem, other softwares show all of my HDRI-s correctly.
Here is HDR photo, which we have tested and which has problems:
Also, is there any chances to see .exr support in jme? EXR seems to be more precise, and it is also good open alternative, I guess. OpenEXR - Wikipedia
We use PBRisComing branch. You can reproduce this problem using TestPBRLighting.java, which contains in this branch. You can replace this line on these examples
I had something similar to the latest screenshot: a storm of red green and blue pixels on a pbr surface.
Does this sound related to your problem? I can’t really tell from the picture, since, there, it seems that the dots are floating or on the screen, while in my case they were on the texture…
When it happened i didn’t care too much since i was working to something else, also note that it was a really old version.
In few days i will probably work with the new pbr and then i will eventually add more informations.
