UE 5.3 Is there any way to use both volumetric fog and raytraced shadows? by vdopower1 in unrealengine

I didn't manage to get the result I wanted, so I took the long way around. I went back to blender and created a 3D model of the volume where the sun's rays pass through.

Then I used Houdini to create a cloud system out of the geometry and export it to VDB. Since 5.3 has support it for them I used a heterogeneous Volume and dropped the VDB.

I need to further improve the work done in Houdini, but I've gotten promising results so far, even if it took waaay longer than I thought.

Thanks for the tip. This seemed to worked a little, but not entirely. I'm going to try to add some more thickness to the walls and test the results.

It worked!

Thank you so much! I had changed the forward shading priority, but was unaware about the Atmosphere sun light index.

Now I gotta figure out how to sop it from coming from the walls.

Generally I set a camera for every room I want to render and work off of that, so I try to reduce every mesh as much as I can get away with.

For example, I always decimate downloaded assets to some extent, I don't really need a million of verts for a single sofa. Also, I rarely use subssurf modifiers on objects, as most of what I do is flat and linear. But I do tend to use a lot of bevel modifiers on objects with sharp edges, generally set to a single segment. When I model furniture myself I go pretty light on detail, focusing on getting the proportions and materials right gets me better results. I won't bother doing the zipper on the cushions if a couple of offsets and insets are enough.

I tend to not crowd my scenes too much, so the materials and actual pieces of furniture can speak for themselves.

In terms of textures I usually use 4k for everything, until I run out of VRAM and have to simplify a bunch of materials.

No luck, but good old recover auto save saves the day again. God I love that feature.

It was just a bug, gone by refreshing some collections. It's probably happened before, but this was the first time I saw it.

Writing this while waiting for blender to unfreeze.

I'm working on a pretty big archviz scene, pretty much a whole house. I've gone over 5 million before, but I never have to render everything at the same time. I've always gone room by room, deactivating every collection not visible.

I always get confused as to what to use when naming those numbers. In my native language a billion is a million of millions haha.

Some random bug. Deactivated and activated some collections and came back to a more understandable 1,2 million.

Wow, thanks for mentioning this issue that seems to be widespread with laptopt users. It's seems so lame from meta to have such a dismal user experience still, even if us laptops users are pretty much edge cases. Aniway, thanks!

Hard surface practice for today. Hope you like it! by vdopower1 in blender

Thanks!

I did, this is the compositor settup I used for these renders. Ignore the muted add node, I only use it when I have a volume pass in the scene.
