Alpha Blend Issues with Lighting


photo

Recommended Posts

I am currently using SDK 2.14.1.1

And i am getting issues with the alpha blend .first issue is whenever I convert an object Material from Opaque to Alpha blend. it drops its color brightness. and the second issue is. Some objects tend to change color and brightness when moved, or Observed from a different angle, or moved under the flooror outside the enviroment prob by half or just a little area of the object.  
The last issue cant be solved by expanding the enviroment prob, but then the reflection for other objects get scaled too. Following are some images and video references for the problems faces. Please if possible provide a Solution. Thank you

This is fundamental limitation of transparent objects and fully deferred rendering. Right now good reflections with transparent objects you can achieve only with planar reflection state in mesh_base (but performance would be really low).

You can also experiment with Multiple Environment Probes option from mesh_base material to improve this situation a bit: https://developer.unigine.com/en/docs/2.15/content/materials/library/mesh_base/#multiple_env_probes

Thanks!

If you can share your test scene with us - we can check what else can be done there for final results improving.

You can do it by packing your data directory (exclude .cache, .ung files and .runtimes directory) into a ZIP file and sending it via any filesharing service (google drive / mega / ...).

Thanks!
