Hi!

Oh my ... texporter eases things so much.

I use it to generate heightmaps out of 3dmax meshes.

But... when loading the heightmaps I get a really bad staircase effect. When looking closer at the texporter generated heightmap I see those steps too in it as it seems to be 8bit only. So I get a maximum of only 256 height levels.

Any way that texporter might generate 16bit grayscale maps?

Just a guess but have you tried the Posterize filter in Photoshop? Probably still steppy but you can add a smart blur after that.

sorry that I missed this post, apologizes.

Unfortunately this is the limitation of Texporter. Although I do interpolations using 32bit floating point per channel internally, since the bitmap I create is a 8-bit per channel texture, the data is lost. There are a lots of things to do piled for texporter. I better start implementing those. Stay tuned.

Just stepped if there's any news.

And... indeed. An answer! :)

Would be just great if you'd implement that ... I digged much in the net and asked in developer forums... noone new a tool that could extract a 16bit grayscale map.

So that feature would be very much unique.

@Supreme_Pizza:
Yeah.. I tried but it's more a thing of accuracy ... want(ed) to use a "normal" mesh for the environment and a grayscale map for physics to fasten things up. Didn't work out of course as 256 height steps are far too few to get a good collision representation.

I've already started the re-write but I'm overwhelmed with Brazil at the moment . Once I have some spare time I'll finish it. Sorry for the delay.
