More precisely, i have tried to modify the texture tiling of differents instanced static meshes, but i end up with always the same tiling for all of them. I was wondering if there are any better ways of dealing with this issue than using double sided faces. 12 and in doing so, I’m re-factoring everything again. if you can find the blueprint that ramas plugin makes you can copy-paste the array data from the ISM actors within the blueprint to HISM actors and they will work If I use an instanced static mesh in a blueprint, does that still support LOD and Occlusion culling for each mesh? So if I have a ton of objects going down a long winding street and make them all an instanced static mesh in a BP, can each mesh LOD to a lower poly individually and stop rendering when occluded by a building. Is there a way to get (instanced) meshes with different texture coordinate The whole point of (hierarchical) instanced static meshes is to be extremely light and performant, they’re not supposed to simulate physics.

This is necessary in my game because: (1) Tile-based terrain height data is read from file to generate vertices, that in turn generate simple skewed 2D planes with Seeing as how this might be problematic sometimes, I did something similar to this to set individual components visibility when they block the view. 25 was the ability to specify per instance custom float data. Using the nodes you’re using, you can do this: image 1469×432 172 Today I show you how you can use the hierarchical instanced static mesh component in UE 5. I'm imagining something like using the HISMs for the grid But UE4 also already has by default a right click 'convert to hierarchical instanced static mesh' option. Assuming it can work with normal instancing, but all the focus has been on foliage without a hint of detail so who knows how we are supposed to handle it. It will be the same sort of thing that you are after but instead of replacing the hit instance with a blueprint actor you replace it will the other instance.

I was trying to learn some methods on how to manage/improve performance in my game and came across a time ago Instanced Static Meshes and Hierarchical Instanced Static Meshes and how they improve the performance and stuff like that, what i gathered from searching so far is that the different between the two is that HISM can display individual LOD's for each Hierarchical Instanced Static Mesh Component not showing. However, it doesn’t work reliably in hierarchical instanced static mesh (it works perfectly in ISM). If I'm mistaken, and that's not the case, you could probably come up with another solution that is the best of both worlds. I have a HISMC and there are some speedtree trees inside. 0 is the default, whereas a higher value increases the streamed-in resolution.
