Static Light Shadows

[anonymous_user_081dc6de1 (BPA3)]

Hello!
I want to light the test scene with two static lights but can’t get “solid shadow”. (((
Tell me, please, what a parameter am I need to get detailed shadows?
Thanks.

Your lightmap UV’s are very bad, when there’s that many UV seams you have too much unused space.

@motorsep

Where did you generate UV1 ? In UE4 or in your 3D app? You can just copy your UV0 to UV1 in 3D app and when importing mesh, uncheck Generate Lightmap UVs.

Thank you very much!

and another trick. If you make an archiviz and want to superfine supersharp shadows - you can use small movable light source. If you can adjust source well - it will not much harm perfomance, but you will have 1 headache less to warry about We try it on our archiviz project, we need sharp shadows in 4 different rooms on 1 wall each, worked fine.

Thank you for your advice, I will keep it in mind, but I’m afraid there are too much lights for “movable”.

You’ll have to remodel the mesh with lightmaps in mind if you want to use baked lighting. Make the grate/vent a plane with an alpha mask. Use normal maps for small details instead of modeling them in. Consider breaking up parts that tile into separate pieces. Try to minimize the number of islands to reduce UV space that’s going to be wasted on padding.

I think your advice is more about the game development, where optimization is the most important thing. My goal is to learn Unreal Engine and maybe in future I will make this scene destructible.
Now I just want to level up my texturing skills and would like to get arhiviz quality picture. I’m afraid that if I bake the ventilation grille to the dome normal map with alpha mask, I’ll need a very large textures to get high qualty render.
Will LODs help me to reduce memory cost? I made a several LOD for each mesh in scene:
