Title: Thruster troubles
Post by: Fozzy on May 14, 2002, 04:15:53 pm

Latley i have been making a new apollo (Aurora) and I am having problems with the thrusters (model).

I made them with normilised rotation at the base of the thruster plume.
They show up ok in Modelview (using texture thruster01.ani)
They dont show atall in freespace.

I found one error that i fixed, i made them so they have got rotation like the freespace models.

you can see the model and a screen shot of my TrueView list thingy here. http://www26.brinkster.com/fargate/pictures/apollo.html

I don't know about the pb, but what I know is that the rotating thrusters on some :v: models are an error, and shouldn't rotate ( they won't ingame anyway ).

As I know the thruster problem is somehow related to the video card and bad texture vertex data generated by Truespace. In some configs it just doesn't show up.

The only workaround I could find (using the Diamond Viper 770) was to import the thruster object into Segeltuch as dxf file, and retexture it face by face. Then I created a POF, and copied the thruster chunk into the POf of the real model with a HEX editor.

I've never used Segeltuch for other jobs, but it's the only prog wich I can make working thruster flames with. :D

clipping pb? now that is weird indeed... I would say you have a pb with your video card ( pb of drivers handling the Zbuffer maybe), but I'm kindda ignorant about this kind of things.
Anyway, why reconverting the ship just for a reskin?

looks like flipped normals to me. Try and select all polies on the thrusters and FLIP´em.
---------
I´m pretty sure they are flipped. Truespace Renders them as they where not, even when they are.
-----------
he i just figured, My guees is that you used the original apollo mesh as base mesh, and that you have used poftocob.exe to get it into Truespace.

Poftocob has some nasty bugs, I quote the creator of Poftocob.
"TEXTURES sometimes seem to come out reversed, i have no idea why"

I do, cobtopof is Flipping some normals(Polygons).

I'm 100% sure it's not that. you'd see at least the complete polys of the other side. plus it won't explain the glows clipping pb.

Flipped polygons are "Transparent" from the outside so you see the opposite sides of from which we are watching, and it seems we are seeing the opposite side while the side we should be seeing is transparent

The clippings occurs because the glow points seems to be inside the hull, or more likely inside the thrusters and combined with the flipped normals this gives these odd effects.

- So I still stand by my suggestion that it is Flipped normals.

Is not the radius of the thruster glowes just simply too big ? :rolleyes:

thanx, I know what it is, I've been modeling for 8 years ;)
this just doesn't look like flipped normals to me, but hey, I can be wrong.
