Hey I went through somethings. I remember now.

it does not mater at all what is wrong with the object or what is right with it. The only way to get a one to one result from TG in MUd is Vector. There is only one way to project the object to a plane, and that will not keep overhangs, and it will not give you one to one results.
Vector is the only way to get an exact replica of a TG terrain in MUd. That is other than a TG obj, but then even if it opens, and you can project it to a plane, you will just get the same results as a height map. And you have to deal with a huge object and memory if the object is to have any detail, that makes it better then a heightmap, like if you render with Raytrace off, to get super details like stones.

I did mange to get a TG terrain into mud via Maya, by a heightmap. But this does not give a 1:1 result. A good way to start a raw sculpt, but then why use TG at all in that case, it is not really a plus.

THe thing is, if I am not getting the work I did in TG to go to mud, then there is not really any point in doing that work in the first. So low res is not a solution. I can make a low res terrain in Mud in 5 seconds. I want to take lots of info, so I dont have to sculpt it.

Quotesounds very very tricky to me.
Sounded that way to me at first too. But its pretty simple, if repetitive. Only two softs needed. And the work flow is basically proven already, just in parts. Vector would bring it all together now.

Now here is tonights effort to get the object into Mud, just so you can see what happens.
The object imports in the normal way, and this warning pops up:
[attach=1]

I then hit "keep all"
And get this:
[attach=2]

Spinning wheel for a while...

Force quit.

Object size was 1.2GB pretty low quality/rez.. IT opens in maya just fine though, can even move around pretty easy. So that should tell us something.
[attach=3]

Oh, one more problem with obj from TG...

So even if you are doing a low res starter mesh to use in another soft, you have to tilt the camera so that it is not straight down. This means that some part of your object has missing parts. As apposed to a height map from tg, which catches everything (within its limitations).

Matt,
Thank you much for delving into this in the open!!! I remember that you said that it would take a lot longer to get per object displacement, and then out of no where we are getting it! I hope that will be the case here too (that vector will come sooner than believed), I really need it.

sadly, I have mostly stopped using TG, I have reached the limits of my abilities to understand it. And I need to use other soft that I understand a bit better to accomplish some of the same things that others can do with TG alone. For example, some of the shapes that people make with functions, I will never be able to do. I can however do that by sculpting them (or painting or whatever). I kinda think about it as way to make any sculpter a plug-in to TG ;D, no plug-in required.

Hmmmmm, a "go Z", go Mud, button in TG?  ;) Well that would be fun anyway. One of the SDK alphas should try that 8)

QuoteHey Ulco, sorry we have hijacked your thread!

No worries; this was just my intention, getting you guys to think about how to export the terrain data from TG for use in other software. Just as a sidethought; photogrammetry from inside TG would probably also work, but a LOT OF WORK; rendering views from several angles, and combining them to a 3D mesh. Strange workaround.

"photogrammetry from inside TG would probably also work"...that is a delicious thought...should be not that hard to implementmaybe 5 camera shots; N.S,E, and W and a top down...I vote for this as an update, hee hee hee.
