Flipbook texture Anti-aliasing
Im creating a 2D animation with the help of blueprints. But the image result is very crispy.
To be sure, I imported the same PNG for tests, and the results are different.
The first one (the one on the right) is a PNG image with alpha converted to a SPRITE. The quality is perfect.
The second one (the one on the left), is a FLIPBOOK with 1 frame, from exactly the SAME SPRITE from number 1. But the edges are differente and more crispy.
The last one (the one on the middle) is a Blueprint with Flipbooks generated from some PNGs. The flipbooks are paused at the first frame. The result looks really terrible at play time.
All PNGs have at least 512px , with alpha and no compression. All settings are set to EPIC. And all Texture dont have MipMap enabled. My camera is Perspective. But with ortographic I have same problem.
Everthing looks fine at viewport. But at play time looks ugly.
Anyone can tell me whats happening?
Really need to solve this one.
So I believe the source of your issue are the texture settings you are using for your character. See the below images where I have highlighted the settings you will want to make sure to have in place for the texture.
Texture Settings - 2D Pixels
As you can see I have made sure to assign it to the correct texture group, and used a Tri-linear filter to smooth out the aliasing of the textures edges. I will say increasing the resolution of the image texture is going to increase the crispness of your texture.
Characters in Viewport
Now both characters are almost identical, and the aliasing is greatly reduced. They won't be perfect as that would take a higher resolution image. You can also experiment with the material and it's clipping value when working with a mask. Using these settings should be sufficient enough to get you on the right path to production.
Let me know if you have further questions.
