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"

Thanks for your reply and sorry for the mistake, i thought that was a common issue :).

The fact is that i've switched the project from 4.19 to 4.20. in 4.19 i didn't have this problem.

In the target hardware i have selected mobile and scalable for 2D and 3D and the Build was in ETC1, i tried with ETC2, ETC1a and ATC too but it didn't work.

The light works perfectly in the editor..

So, here is the project details :

Material : Blend mode : Opaque Shading mode : Default lit Lighting : Volumetric non directional.

Light: Directional light : baked

Device: Huawei P10 Lirte and Android Version 7.0

Try to add default materials and light and make another build and see if it will work .bec it could be a shader issue , since I dont know how u made ur shader.

it didn't work :/ it seems to be the camera. for exemple, when i jump, the strange color shape follow the movement. is it possible ?

disable post processing on the camera section if u enabled it . also check if u using mobile HDR or not, try to turn it off and check again .
