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"

Colour Issue. Texture Compression?

Hi,

I'm getting this strange green-ish artifacting on my imported texture into UE4. I'm just wondering if anyone can tell me the cause and/or fix for this. I'm wondering if it's something to do with the texture compression but I'm not to sure. It's a 2048 texture map.

Thanks for your time.

That is typical dxt1 issue. It's use 5bits for red and blue but 6bits for green. This causes green channel act just like that. You can try to use BC7 texture compression settings for that texture.

Hello,

I know I said yesterday that switching to BC7 texture compression fixed the issue I know realize that it has not. I had defer texture compression ticket.

Even when the texture compression is set to BC7 it is still doing the issue. alt text alt text

Any help would be greatly appreciated! Thanks

Can you show texture after compression. Don't use JPG because it's also have all sorts of artefacts.
