Why my glass material look red on shader complexity

i made a glass material and it looks all red on shader complexity did i do something wrong or is it just how shoud it be. so if i did wrong, how can i improve it

Thx for answering this beginners question. i am about to submit a project so i needed to know thanks again

It looks the same for me. I don’t think you’re doing anything wrong, it’s just glass is computationally expensive. Try not to use too much if you want a high FPS.

Thanks for your answer. so best i can do is use less windows to make more optimized levels

It depends on what hardware you are targeting, in general you can use transparent materials just fine, just don’t overdo it.
Things like replacing the glass material with a non transparent material on a lower LOD can help but if you are not experiencing performance issues then it is not something you need to do at this point.

Basically make it look as good as you can and dial it back a bit if you are starting to experience performance issues.

GE_Peter’s answer is correct. Anything with transparency is more expensive and when you have multiple layers (looking through glass object 1 to see glass object 2) it becomes even more expensive. So use them in a smart way. In general it is not a superbad thing to have happen but as soon as they start filling up most of the scene with multiple layers you are starting to play a dangerous game.

oh it’s a good idea to make a material just looks blue-ish and put it to LODs settings thanks for help btw
