Just to clarify @SwitchupYT, setting the LODBias sets the rendering parameters to bias to that level, but it does not affect your upload. If you have a 4k texture, set the bias so that it renders at 256x256, you still have to upload the 4k texture. This impacts your upload size.
What @LittleGiant proposes is to change the size of the imported asset so you’re uploading to save up upload.
- If you don’t have the source texture, Set the LOD Bias in the asset.
- Execute the Resize Texture Import Data above.
Your texture should reduce in size! I noticed that when I did this process, the material I created became unusable and I had to delete and re-create it. I’ll log a bug. Let me know what you find.
