Hello all,
Diving into Shaders with Strumpy lately and I’m trying to make a simple shader for a mobile game. The shader pans a texture over time. I used the “uvpan” example that came with Strumpy and it works ok. Except when you let the game run for 5+ minutes, after that, the texture will become blocky and panning becomes more choppy. My only conclusion was that the unity Time property was losing precisions as time passed.
So I tried to add a Modulus % operator in Strumpy to loop the time, but I couldn’t find it. I don’t think there is one, (correct me if I’m wrong)
So now there are two things I have found. I can still use Time if I subtract it with it’s floored self;
NewUV = UV_Cutoff * (Time - Floor(Time));
And this solved the blocky texture problem, but the panning still becomes choppy!
Another method I tried was writing a script to access the materials and reset the _Time property back to zero. And this method works flawlessly. But now I have a script on every game object that uses this material/shader. Is there not a better way? How does one properly use _Time in shaders for mobiles?
