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"

Why the map looks more bright and warm on pc than on mobile?

Hi guys! I'm puzzled that the light and shadow looks great on windows , but everything seems to be changed on android and ios. Just like the three screenshots below , the leaves looks bright and clear on pc but so dark on mobile . The texture reflection doesn't works at all , why does it happen? Maybe the deviceProfiles , lighting or any other rendering settings? How to achieve similar result for pc and mobile? Thanks!

On android: alt text

On ios: ![alt text

Different rendering capabilities. Mobile doesn't support the same post effect and shadow quality that you'll get on desktop. Also on each device you're going to have a different color profile for the screen which is why the colors might display differently on each device. Strange to see that sign in the foreground rendering in a teal blue as opposed to the purple it shows as on windows and Android though. Usually the discrepancy won't be that extreme.

Actually, I just realized that the iOS screen shot was taken from a completely different location in the game. You should try to take a screenshot from the same place.

I thought it was strange for the color profile to be so different on iOS. Yeah, so it simply comes down to rendering capabilities. I think iOS supports some basic reflections but not the same that you'll get on PC. Also the way materials render is going to be different so you'll see some discrepancies there as well hence why the trees look darker on mobile.

Personally I'd suggest you build for your main platform first (either mobile or desktop) and then create a duplicate project where you tweak the materials etc. for the other platform. IE develop everything on Desktop First, package your project and then go through and tweak the materials so they give you the same look for mobile and package that or vice versa.

This is the best way to avoid an inconsistent look on each platform. You'll notice the rendering quality on iOS and Android look quite similar to each other. This way you can also go through and tweak the lighting on mobile so that it looks closer to the desktop spec. For example in the current scene you could add in some supporting warm lights at the archway.
