View Full Version : XSI: Maximum Texture Size?

Is there a maximum texture size allowed by XSI 4.0? I'm running into a problem that has really stumped me.

Here's the setup: I've created a sphere surface, I've given it a phong material and a UV texture projection. The texture I am using is a very large and highly detailed diffuse map of Mars, an 8192 x 4096 4.92 MB jpg.

I'll use my node map and add an image node, load the texture, and then plug it in the the diffuse plug of the phong material. Unfortunately, no matter how many different combinations I try, it only loads the default no icon pic. Even in the texture node, when I first load the image, it will say "click here to load" in the preview window... and when I do, it displays the noicon pic.

Argh!

How come its so big ? What are you using it for ?
You might have to turn it into a .map file, but i think XSI4.0 will do that automatically, theres a switch somewhere in the render options/Optimization tab.

Good luck

Maybe your display card wigs out at displaying such latge textures ? Does it render correctly ? If not, then XSI might not be recognising your .jpg file, try re-encoding it without any of the optimisations or progressive. Or try the .MAP format, which you should be using for large textures anyway to reduce RAM usage...

Jpegs of any size of 4096x4096 can be a serious drain on video hardware. I've noticed this to be especially true of my ATi (radeon 9700 pro).
Convert the format to say a targa or a map file and try that.

Woohoo! Thanks guys... I turned on the feature that allows XSI to automatically create a memory mapped image file, and suddely, everything is hunky dory. :) Though my sphere is still textured with the default noicon pic in the viewport, quick render shows that the texture is working as advertised.

Outstanding! Thanks a lot!
