All I want is a sprite in 3D space ...

… and the grief I’ve gone through is enourmous. :smiley:

Nevertheless, I’ve gotten it this far. Now, I’ve got the texture using the image alpha, and the material has an alpha of 0. In the material preview window, it’s a perfect cut-out; exactly what I want. But then I render and I get the whole quad filled in …

Any ideas what I’m doing wrong?

EDIT: Hmmm. The background color in the texture itself is pink, and I can see it poking in through the edges … I need to fix that too, but that’s trivial …

EDIT2: The color used for the filling is the world BG color apparently, if I delete the world material, it becomes black …

EDIT3: Almost got it …

I turned on raytracing transparency. I’m mildly annoyed at the line still slightly visible across the top of the polygon, but even more annoying is the shadow. I assume I’m just plain out of luck there? Because that would suck. :frowning:

press trashadow on the recieving layer

then ray shadows can use the alpha of the object

also, set the repeat mode for the texture to extend [iirc] to get rid of that line. you may also want to turn off InterPol

a) Thanks, and b) did that already.

Excellent! Though a little annoying that I’d have to individually set that option for every material. But … a new problem has arisen …

Can those ugly coloured artifacts be fixed?

EDIT: Enabling raytracing for transparency rendering on the floor as well as the sprite decreases the artifacts, but doesn’t quite eliminate them …

Bah! Another problem on top of those colored artifacts …

Should I just make a grid and color the squares with different materials? %| More work and more limiting, but I can say it works. :wink:

(I’m kind of trading one problem for another there; reflective surfaces don’t seem to show the colored artifacts. But then you see the quad. Bah …)
