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"

textures look pixelated on Android

Hi, When building our game on Android many of the tiling textures look extremely pixelated. I have included a screenshot from the editor and from my device.

The problem is caused by using tiling materials and it can be fixed to some extent by decreasing the tiling amount (in a texture coordinate node in the material editor), decreasing the scale of the UVs and decreasing the number of verts in the mesh. Unfortunately this makes it very hard to work with though - I need to be able to tile materials! After a couple of days of investigation it seems that this is quite random, and the pixelation can look better or worse. I think in general it seems to get worse the longer I play on Android (it deteriorates over time). It is also much less pronounced on newer device (an S7 doesn't seem to do it at all whereas an s5 does all the time).

This is on PC (mobile preview) alt text

And this in on Android device (note the grey wall texture at the back and the arrows coming out of the cannon) alt text

The problem also occurs on moving textures like water (anything that is panning in the material editor)

On mobile preview alt text

and android: alt text

I'm guessing this is down to some kind of floating point inaccuracies but some clarification would be very helpful, and a fix.

Many Thanks
