Thanks for your help, jsmack. After wrapping my head around it once more i now understand the cause for my issues. Maybe my last post was a little misleading because i actually need the mantra render as final output.
Since the Indie render output is max 1920x1080, the texture on the dome (which only has a percentage amount of this resolution available on the final render) would be downscaled and thus, of course, looses detail from the original source. So i guess the only option would be to render bigger images with a full license.
These renders will be projected/beamed on a real dome by 10mtr diameter and artifacts can unfortunately be seen much better then at large scale…
Thanks again for your help! markus

Yes, it is with mantra. I guess at least in the viewport, the texture should “look” as detailed as the original “texture.png” but even if i project it on a 16x9 grid a lot of detail gets lost with my setup…
Maybe it is a limitation by indie license?

Hi everyone. I have a very basic question regarding the quality of image textures.
I have a 360° panoramic image, rendered in another application, which i want to use in houdini as texture on a half-sphere.

So far, i got it working with principled shader (base color texture) and a uvproject sop.

But, no matter how high the resolution of my image is (4k/8k), if you zoom in a little, the texture on the sphere has big staircase artifacts.

Would be very glad if someone could help me to improve the quality of my textured sphere.
Thank you, Markus
