Hello !
I am posting about a problem that is persisting while building light in unity hdrp with default setup, i keep getting rough patches of indirect light in this simple room i am building light for that doesnt go away no matter how much i increase the lightmap resolution and indirect light sample (I also tried with texture 4096 and with indirect light samples 4096). Another issue is the alas of the sahdow is so bad :
Any provided help would be much appreciated !
Looks like dilation/texel validity artifacts. Have you seen this post? Lightmapping Troubleshooting Guide
thank you for your reply i ll check it right away
it looks like that is the problem but unfort, the proposed solutions are not working and the invalid texel view shows all in gray instead of the green and red map :
Which version of Unity are you on? On older versions, the texel validity view will only show any data in the same editor session as a bake was performed. In other words, to see it, you might have to rebake the scene, unfortunately. You can also try the proposed fixes in the post I linked blindly, if you’d like.
Thank you ! I m using 2022.3.34f, latest stable version, I managed to solve this although by indicating to unity to generate the lightmap UV under model import settings, appearently it doesnt do that by default like in unreal engine so one have to check it :
