Sv Pilot	posted 11-22- 07:54 PM Ok, I'm making good progress thanks to all here, now we come to the tough part: texturing. For the love of all that is holy, could anyone explain to me how to texture objects using the tools we have? (OPS, AC3D, Hippie's tools) For starters, how do you add a new texture to the SM file? OPS can not do this now, right? I have tried adding a new name item and new texture item - then using it in a LOD- but it fails for me. Is there a trick? Next, how do you wrap a texture around multiple polygons? How does that texture mapping work? Can it be done with thetools we have? If I could only figure this out I would be on my way to getting a real live plane done! Any help on the topic would we especialy appreciated! I'm desperate here guys! Guys? heheh... you get the point - spill it! Talk! Anything you know.... Thanks! ------------------ -Sv =FC= IP: Logged
Bryan Russell Pilot	posted 11-23- 08:28 AM OPS does it implicitly. If you export a .MTL file with the .OBJ, file, OPS uses the material information contained in the MTL file (well some of it anyway) to map each polygon, and will search through the list of textures in the loaded SM file to see if it can find a match. If it doesn't it will make a new texture entry with the texture pointing to: "./{aircraft}/textures/{texname.tif}" You'll need to put the actual texture in this path. Actual texture mapping is all in the 3D package i.e. AC3D 3DSMAX etc. I think you'll find that once you find the UV mapping stuff in AC3D (or whatever) and use it a bit it'll turn out to be quite simple. If you need any help with generic texture mapping I can help with that but I'm afraid I know nothing about AC3D.

Sv Pilot	posted 11-23- 09:40 AM That is good news Bryan! I do need an insight to general texture mapping if anyone has time... but don't sweat it if you are too busy. Just knowing that I should look into using AC3D to texture map is great info! Do any of you AC3D users know if Hippie's LOD import/export supports texture mapping? Any tricks/tips? Thanks! What does UV mapping do exactly? I'm getting there heheh... ------------------ -Sv =FC= IP: Logged
Bryan Russell Pilot	posted 11-23- 03:59 PM I'm sure it does, the LOD contains all of the texture info. IP: Logged
nuum Pilot	posted 11-24- 04:04 PM Sv, I am trying to understand the UV mapping world with UVmapper : http://home.pb.net/~stevecox/boxtut.htm Don't forget our plan. We will rule the world !!! nuum WWI aircraft IP: Logged
Michael Pilot	posted 11-25- 01:42 AM This is how you texture in AC3D: Load your texture as a background image in one of the ortho views. Then create a rectangle the precise dimensions of the background image. Load the texture onto the rectangle. (Because you gave the rectangle the same proportions of the texture there will not be any distortion. Next, you postion the rectangle in line with the part you want to texture. Scale the rectangle so that the textured image is just ever so slightly bigger than the part you're texturing and make sure it's lined up properly. At some point you should also load the texture onto your object (which should produce a colourful mess. Then select both objects, switch to vertex mode and remap the textures. Your object should now be properly textured. If download the non-beta version of AC3D it contains a manual that explains it in more detail (with pictures). Before exporting the .ASC file you must make sure that the "shininess" value for the colour of your part is set to a number that corresponds to the texture index in the .asc file. As one colour can only have one shininess value, when you import a plane, the various bits are several different colours. The actual colour is not exported out. The only problem I have is that some of the time I can't get textures to show in the ortho views. If they don't show, the whole process is more or less impossible. IP: Logged
Kraftwerk Pilot	posted 11-25- 12:32 PM I keep getting crashes when loading background images to use as blueprints..they are 200-350 k gifs from adobe photoshop 4. Is there a limit to how big they an be in Ac3d? I have the unregistered version. IP: Logged
Michael Pilot	posted 11-25- 02:03 PM I export .bmp files from a draw program I use and load them as background images and have never had a crash. I have noticed that bigger ones can take a long time to load (around ten to fifteen seconds). IP: Logged
Sv Pilot	posted 11-25- 05:06 PM This is Great info! Thanks Michael! ------------------ -Sv =FC= WWI in SDOE! IP: Logged
Sv Pilot	posted 11-25- 05:17 PM How do I make the bottom of my wing a different color than the top using this technique? I take it that using this process you must always map 1 texture onto 1 object. There seems to be no way for AC3D to texture sperate surfaces of objects with different textures. You can only export 1 object as 1 LOD at a time right now... When you texture this way, does the back side of the object just get the texture inverted? If I texture the left view of my fuse this way, what will be on the right side? Thanks! ------------------ -Sv =FC= WWI in SDOE! IP: Logged
nuum Pilot	posted 11-25- 05:42 PM Sv, i - Enter AC3d ii - Create a box iii - Vertex mode - select the four vertecies (right side) iv - Surface menu - cut-away object v - MAINTAIN IT SELECTED IN THE GREEN BOX(very important)this surface is now an object vi - Object mode vii - Object menu - texture - load texture This way only the selected surface will be textured ! nuum WWI aircraft IP: Logged
Michael Pilot	posted 11-25- 06:10 PM Not sure I understand the last post. All I do is select only the surfaces that I want to texture if I'm doing only part of an object. To select the surfaces I go into the 3d view and use control shift click to select them. I never make an addtional surface object. IP: Logged
Bryan Russell Pilot	posted 11-25- 06:41 PM The AC3D stuff sure does look complicated compared to MAX. IP: Logged
Sp@nky Pilot	posted 11-26- 01:51 AM bryan i have tried both and i like ac3d cause its simpler i was making stuff in 5 mins in ac3d i never did make anything in 3dsmax prob depends on what u start with IP: Logged
