Hello,

Please could somebody tell me if there is a procedure or writeup somewhere that would help me figure out how to make a domed walkmesh helper? (I.e. a 120 degree horizontal slice off a sphere.) All I've found is the MDB file layout description and some indirect references. I'm assuming I'd need to use Blender to make the mesh, but then I'm not sure how to convert that into the WALK component of the MDB file.

Thank you.

I don't know, but I checked the placeable walkmesh helper object properties, and tried replacing the meshes with a domed one.  When I brought it into the toolset, there was a grey box (texture not assigned), but the C2 and C3 was there, so I tried baking, and I got a partial dome walkmesh, with the rest being that white square around it, which usually indicates too many placeables.  Maybe too many faces in the walkmesh.

Interesting. I wonder if simplifying the mesh would help? I wouldn't think it needs to have more than a couple of dozen faces.

I have/had a walkable dome I used for flying and levitating. simply sfollow the standard WM helper tut and you should be fine

[rjshae]

Okay, well that's what I came here to find. Please can you give me a hint of where to look? None of the tutorials seemed to be about making a new walkmesh helper.

somewhere on their site maybe?

or try to modify a flat one with 3dsmax8 and the mdb plugin??

you could - in theory - make a pseudo-dome with multiple ramps sized just right

I did look there. The closest I found was the placeable conversion tutorial, which assumes you have 3DS. All I have is Blender, unfortunately.

Placeable Tut
Don't make a visible object, just make the Walkmesh, C1 and C2 mesh.. If you do add a model flag is as invisible (not rendered). I have no blender tutorials

Thank you. Wish I had 3DS...

[rjshae]

Okay I think I've cracked the code on this one:



Ta-da! A floaty platform, both baked in the toolset (left) and in the game (right).

The secret seems to be in how the extreme negative Z values are handled. The bottom ones along the sides are set to the special value z = -1000000. However, if you sub-divide the mesh in the model then you end up with some vertices at, say, z = -500000. When the model is loaded into the game, the -500000 value gets treated like a real coordinate, so bakes fail. But if you massage the sides so that all the vertices with deep negative z-coordinates all extend down to -1000000, then the bake works. (I trim the extra meshes along the sides to just a single layer of triangles, then extend them down to the required value.)

Now I just need to figure out how to simplify the upper part of the mesh...

That's GREAT. Not sure I understand the z= negative one million part, but having tried and failed a dozen times in 3dsmax, I gotta say I'm thrilled somebody figured this one out.

[Morbane]

good work rjshae!

it is sizeable as well?

[rjshae]

Yep, it's sizeable. Baking can be a bit of an adventure, but it works. Thus far I have a platform and an arch working for both stone and wood.

Anybody have a basic shape they'd like for a walkmesh helper? Simple shapes with a low mesh count seem to work best.

Thanks. There's a writeup on the MDB Format page that describes it.

I was trying to alter the "ramp" style walkmesh helper that nobody seems to use, but I do actually have a very specific use for a dome and for ramps which are concave/convex. My wildest dream would be the ability to assign a texture to that, counter-intuitive though that is, but all of this is great.

[rjshae]

Do you mean a cylindrical concavity/convexity? How much curvature is needed?

[Happycrow]

Yes, that's exactly what I mean. Wouldn't need to be a whole lot, just enough to distinguish it from the already-existing purely "diagonal" ramp. Basically I can play with dimensioning to get the rest going.

[Morbane]

WOW.

rjshae, a walkmesh helper pack!

it has indeed been a really good day!

Happycrow - the best use i got out of the ramp was in the cave tileset corner tile with the hole in it - i used the ramp to spawn sahaguin in the hole then appear to climb out of the water - i actually managed this with the flat one together with the ramp - yes i know - doesnt seem possible since WMs are so tricky - but it worked

[rjshae]

A problem I'm finding with the platform is that the point you click on is relative to the floor underneath, rather than the projected platform top. That makes it unusually difficult to navigate. Perhaps it would work better if I build the helper with a plain top surface but no sides? That way it could be made to work with placeables by putting the surface just below the placeable top. Maybe a semi-transparent, tintable, random noise surface? I'll have to do some experimenting.

I'm tempted to do a Blender tutorial on WALK meshes... once I master this thing a little better.

[rjshae]

As an experiment, I created a flat, L-shaped walkmesh helper and used it to build a matching dock with a pair of walkable ships along the sides. It worked!

Dome-shaped walkmesh complete and functioning.

[PJ156]

Good work RJ, that tutorial would be useful if you get to it.

Do the dome work on a tile set interior?

PJ

[rjshae]

It should work on an interior tile set, but I'll give it a test. Thanks.

It will. Walkmesh helpers have priority over the tile walkmesh. You can even use them to walk through solid tile walls (I did in Crimmor) and above the ceiling.

Is this about what you're looking for?

Convex ramp

Hopefully you can see the mesh okay.
