[SOLVED] 3DC Demo crashes and terrain import question

hi there,

 

I am on a 3DEC trail, to see if it will be a useful piece of software for me or if I had to look for another sculpting tool...

 

My main interest in 3DC is sculpting, re-topo (auto) and UVing. For painting I´ve got other tool, already.

 

Now, I´d like to import an .obj file (a terrain, generated within Word Machinw, about 5Mio polys) - but it seems, like this

is just too much for 3DC. I am using the win-7 64bit DX cuda version.

 

A collegue of mine got a similar rig like I own (i5, 8GB, 2GB GTX 770) and he opens the same terrain obj file in Zbrush in under 20 seconds...

 

When try to open it as "surface" - I get "out of memory error" and you can see, one CPU core is at 100% all the time.

After that, 3DC crashes...(Bug report sended)

 

 

I also tried to import the heightmap (16-bit tiff, also from WM) - but I just get a flat surface, no terrain... I already tried to scale up the height, but

no matter.. still get a flat box :(

 

If there is no way to get the terrains working, I will have to buy Zbrush or Modo - which will be priced much higher, but seems like it´s worth the inverstment, unfortunatly a high one for a hobbyist...

 

 

Kind Regards

My test using png output and a 512x512 terrain size

next steps

mark seams - unwarp - bake with PPP - paint

Hey, thanks for quick reply and testing...

 

Ok, I use 2048x2048 heightmaps (2049x2049 to be correct) -  seems, 3DC works only with 512x512 (like in your example) - but this is too low res for my needs.

 

Cheers

 

 

edit: it works now! maybe using PNG instead of TIFF was the key, here ;)

 

edit 2: ouch.. it´s very "terraced/jaggy".. maybe PNG is just 8bit, instead of 16... 

 

edit 3: Hmmm, PS says "16-bits"

Meanwhile, I exported another mesh (490MB, 5Mio poly), which also crashes 3DC... tried "quad-export" option in WM an also without (exports tris)...

That is a big problem... maybe I should really make a ticket (just write Andrew a mail)?

ooookeeyyy... it´s 500MB file, will upload it over night and report the issue tomorrow, when upload is ready (slow internet atm)

 

tested 64bit DX and GL (without CUDA) - same crash and "jaggy" terrain, when import a heightmap (tiff will not work (!), but png)

 

Cheers!

Hey, that is good to hear :)

 

Ok, but I dont want to paint on it - instead, I´d like tune/work on the real mesh - is there really no way?

I´ve already managed to load in 5 objects (above 4M tris total) with "repair scan-model in surface mode" and/or "scene in surface mode"), then "voxelized"

them and merged them into one singe volume of about 2M tris.

 

3DC handles this without any problem or stutter...

 

So I thought it would handle 20-30M polys - this is not intended kind of use?

 

 

Best Regards

Back with a new result...

 

I started with File->new "surface-mode scene", choose "empty grid" and then went "File->add model to project", picked the 500MB obj... aaand BOOM -there it is.

This way it works 100%, tried 3 times now - no crashing, all good now!

 

So- what did I wrong all the time?

 

Before, I went File->new "surface-mode scene" then clicked on the "Folder" and picked up the obj

 

Why is this result different?!

 

 

Best regards

In the bus model there was unusual normals packing, so coat was crashing. Mountains are probably just deformed patch, so it dows not crash.

Follow beta thread - I will post build there relatively soon (I still have several problems on plate before making build).

I still recommend File->Import for vertex painting

Dont know what "bus model" you refer to... For the normal maps: When I open the mesh in the 3DC GL version, normals are ok

, when opening in DX version, normals are flipped - so I do not see a problem here.

 

Ok, will have a look at the beta thread.

Do not let this distract you, take your time!

 

Best Regards
