Rotating texture proportions questions

hi !

i know that i resolved once this thing, but i m fighting it again:
i have a texture image ( 820 x 635 ), sized to be stretch to the rght proportions. it contains a circle.
When rotating the picture the circle becames ovoid .

how can i do this ?
or is there any node taking in charge this problem ?

yours ;-)

Use AspectRatio (Transform) with the size of the renderer into the AspectRatio input of the renderer

AspectRatio.v4p (3.8 kB)

thanks sunep !

Then working with textures you can also use Billboard (>Pixel). Here is an example, which uses different basis transformations as well. (thanks to joreg) (74.6 kB)
