I had been working on my artstation challenge for a while.
when I tried to uploading the model / texture from substance painter. I noticed the texture compression issue.
Here is the sketchfab link :
so if you look at the chest piece you will see the bad texture compression.
This is the original texture before compressed to HD :
This is the HD version :
There is a little bit bump dots on the metal piece .
I tried to find out the reason. First I thought i did something wrong with the texture
but I am sure that its the texture compression
- If I upload the model with jpeg 8bit textures, the bump spots show up
- If I upload the model with png textures , the bump spots will not show up BEFORE textures convert to HD or LD
Normal map texture format comparison : (crop from 2k texture)
You can easily tell the difference ~
No matter what formats I try to upload, I assume they will all converted to jpeg 8bits for HD version ??
I know other artists bought up this topic before, but I am still hoping that Sketchfab can solve this.
If there is a way we can choose our own starting texture version when we show people our portfolio pieces ( uncompressed , HD, LD ), should that solve the problem ?
I do understand I can add " ?imageCompression=0&preload=1&pixelBudget=02 " after the link , so i can share the uncompressed version, but I can only do that when I am sharing individual pieces with the link.
Any thought ?
