DR ASE Blend Exporter

[Obsttorte]

• I was using a completely flat patch.
  
• what do you mean, I assume your not refering to the texture/scale controls in DR as thats not possible.
  

• whether the patch is flat or not does not play any role
  
• I mean shader parameters to be included in the material definition, for example
  

{
 blend diffusemap  //blend mode
 map texturename  //name of the image to apply
 scale 2,2  //decrease size by factor 2 in both x- and y-direction
 rotate 90  //rotate the texture by 90 degrees
 vertexColor  //apply vertex coloring
}

Ah cool, ta.

[Bikerdude]

Apologies for not doing the video tut over the weekend, i will try and do it this evening.

[Bikerdude]

Ok, having a problem. Im trying to put the ambient stage into the material def, but no matter what I try it breaks the blend script.

Try adding vertexColor/inverseVertexColor to the ambient stages.

[Bikerdude]

Ok, will try this this evening, if it works then its good enough to hand out the community along with my video tut etc.

[STiFU]

Oh yeah, having vertex colored ambient blend stages was actually missing from the initial forst-map release. Now if I could just remember where I posted the corrected material definition...

[Bikerdude]

Evening

 

As promised a video tut of how to create a bit simple blended terrain, enjoy.

Tried following my own instructions as show here, but when I try to export ist isnt working as the resuliting model looks as follows -

 

 

 

And ideas whats going on as this should work as it did when I created the tut linked above, nothing has changed that I can see.

This is what i say "thinking outside the box" fantastic work Obsttorte.

@Obs, any idea on the above..?

[Obsttorte]

@Biker: Seems I've missed that, is this still actual?

[Bikerdude]

yeah last time I tried it a few weeks ago.

[Obsttorte]

Can you upload it?

[Bikerdude]

Yup, here you go.

It seems you've accidently exported the model with the default ase exporter, as the blend exporter does not export surfaces textured with the common/blend texture.

 

Using the Ase blend exporter gives me this result:

[Bikerdude]

well the textures are the wrong way around, the cobblestone should be on the bottom, but I know I clicked on the correct export script.

[Obsttorte]

Regarding the textures you would have to change the material file (exchanging vertexColor and inverseVertexColor) or place the blend brushes differently.

 

However, as said the blend exporter does not export the blend surfaces, therefore you must have used the wrong exporter.

[Bikerdude]

@Obs, what's causing the following artefacts on my blend patch model..?

 

[Obsttorte]

No idea. This normally only happens if patches get stretched very strong, which isn't the case here.

[Sotha]

I've seen this too when I made some modules. Sometimes a vault arch looked okay in DR as ordinary geometry, but when I made it into an .ase model, sometimes some parts were darker.

 

From Blender model making I,have the feeling it has something to do with extra vertices in a model: cleaning extra vertices fixed the darkening. Or wait, maybe it was because of incorrect smoothing groups? (I'm no specialist, but Arcturus or someone else modeling specialist would probably know the cause off-hand.)

 

In DR, however, we cannot just go and manually remove vertices, or manually adjust smoothing groups.

 

If it is because of vertices, you could play with the patch inspector. If you have manual tessellation, set it to auto for the patch and try exporting again. If you have it already on auto, switch to manual tessellation and test different settings. Perhaps you will find a setting where the black spots are minimal?

 

Also, what if you just move some of the vertices in the patch mesh, just a bit, near or at the blackened spots. Perhaps slight adjustment fixes the black posts when new vertices are generated?

[Bikerdude]

thanks Sotha, I migtht even just creat a single patch instead of the current multiple patches.

[Springheel]

My guess is a smoothing issue centered around a single vert.

[Bikerdude]

So if I open it into blender and just hit smoother verts it should fix the issue..?

Smooth shading, not smooth vertices.
