Unify the use of UVs in the Sprite variants

[Thomas_Helzle]

Since I was getting grey hair over this, I thought I should make one of the issues from my epic thread on text-particles into an FR:

At the moment, there are two kinds of Sprites, the "Sprite (Material Extension) and the "Sprite (Effect).
The Sprite Effect has the “use unified UVs” enabled internally and behaves as one would expect from a billboard, having a 0-1 UV range over it’s surface.

Initially I used the Material Extension, and there you get a different range, so I was seeing 4 words instead of one as I would have expected - and also the UVs are flipped in Y compared to the Sprite Effect.

Here is an example patch, created from the original help file @Gegenlicht created for me when I was unable to get it to work. It’s heavily modified to make the issues clearer and also has a fixed FlipBookUV replacement inside.

My request would be to unify the two sprite variants and make them behave like the Sprite Effect, so they work out of the box with the (fixed) FlipBookUVs.

I personally would also suggest to NOT make the aspect ratio for the Sprite a hidden parameter… ;-)

Thank you very much.

For reference, here is the epic thread leading to this:

Continued from Chat: How to attach text/words to Fuse particles

Continuing from the VL.FUSE chat: I was fighting with broken renders from a spritesheet that I applied to sprites via the FlipBookUV node. The issues I had were: a.) if I had the same values for X and Y for both the spritesheet generation (in my case 6 x 40 cells) and in the FlipBookUV, I got four words per cell instead of 1. b.) if I doubled the subdivision for the sprites, I got most words correctly, but some were half a sprite offset. c.) only the first couple of rows were used, not the …

Yes you are completely right I reworked those parts on the sprite nodes and they are now consistend in uv handling.
