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"

Rendering problem of Spite and Images on low mobiles

Hey everyone,

I habe a massiv problem, I packaged my project always for my htc one m9 and it worked fine on this mobile. Then I wanted to publish the game and then i got feedback, that on other mobiles the game doesn´t work. The game starts fine and the splash screen is shown. After that the menu appears but the images (with alpha) are not shown. instead of them the room they take nomally ist white. When launching the game there is the same problem, the sprites (also with alpha) are not shown correctly. but static meshes with normal material. But the game logic works fine.

I used etc2, the same as I have done in 4.8. Just that it worked there. I also tried to use the multi- mode but it didn't start on the mobile.

ETC2 is not supported by all GPUs. ETC1 is the only one guaranteed to work.

I found the solution with your help! My first fault was that I packaged the project in etc2. The second problem was, that I used one high resolution alpha image that was to much for the device - thank you a lot for your help! I´m happy now :)

Which texture format did you use? The HTC you mention is Adreno based. Note ETC1 does not support alpha so any alpha based textures will be uncompressed.
