Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Material not loading fast enough

I have hundreds of static mesh actors and hundreds of materials. I'm using the Set Material blueprint node to assign the material to the meshes.

When I run my project, I notice that all my meshes appear grey! alt text

I know that my material is definitely being set (because the original material was the white Default material), and it looks like the material simply hasn't loaded.

Is there a way to work around this?

(The material actually shows up on some of my meshes, but it doesn't show up for the majority of them)

The problem could be that your VRAM isn't keeping up with the project. Are the objects really high-poly? It would help if you post a photo of the blueprint of your material, as well as the scene it's in. Let me know the specs on your computer and I can probably figure out if that's what's keeping you down.

Each mesh has about 33,000 triangles, and there are a few hundred of them in my scene, although they're already placed before run time. I'm simply assigning material at run time.

Here's a photo of the material BP (I didn't do anything to it). alt text

There's literally no scene. It's just my mesh/texture in the middle of the default plane. Here's a picture anyway. alt text

Thanks tedshrop~!

Does it work when you assign the texture before runtime? Or does it still not work. It's a good thing to check because it will eliminate the possibility of it being a problem with the texture or mesh.
