Resize Texture and Apparent Diameter

Post #1by JDicus » 25.12.2004, 14:25

It was necessary to change some 4k and 2k to 1k textures on my computer. Is ther a formula to change Apparent Diameter to be compatible with the new 1k size????

The apparent diameter display is completely independent from texture sizes, and only related to object size, observer distance and fov. Smaller textures only lead to coarser display of surface features.

Texture Resize

Thanks for your reply!
Santa didn't bring me a new Video Card so I must resize.
I resized the Billboards to 1k, I assume no settings need to be changed to have them appear the right size.

I just installed this program, kind of interesting!

Large learning curve, I looked into scripts and there doesn't seem to be a code generator. So I'm trying to write one if I can figure it all out.

There doesn't seem to be a sound command to play an audio file. Would be nice to integrate MS or some other sound and movie clip player.

That's right, as long as you size them to dimensions that are a power of 2 you should be fine.
