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"

Change Texture Format for Mobile - 4.10.4

Hey there:

I am working on a mobile project and everything has gone fine until getting to the materials. In past projects for mobile, I have been able to build and deploy successfully. This project builds fine, but it crashes after the splash screen. The only difference that I can find is when I hover over the textures in the editor, the old successful projects show the format as DXT1. The new project that is crashing shows the format as B8G8R8A8. Can anyone give advice on how to change this either in the editor or in photoshop? Attached are two reference photos to show the difference.

Thanks, Bradalt text

Hmm, not sure why, but reducing the textures to 1024 instead of 2046 has now changed the format to DXT1 from B8G8R8A8 when reloading. Either way, the project runs successfully now. It would still be great if anyone could inform me as to why this happened or what the difference of the formats are.

Thanks!

The reason the 2046 didn't work is that it's not a power of 2. If you had made it 2048, it would have worked fine :)

Dang! I did not catch that... I started with 4098 for PC, was moving it down for mobile and missed the numbers. That would make since that the format changed as well.. Thanks a ton

Yeah, you will want 4096, not 4098, on PC :P
