View Full Version : 3ds max can't get uvw map to behave (with pics)

Hi,

I'm pretty new to Max and I've recently started to learn about uvw mapping. However, I'm having serious problems trying to resize a texture so it looks right on the poly's I've selected.

I've attached some images of my car to show you what I mean:

The Texture:

Where it's going:

The way I've been trying so far is to open up the texture as a bitmap in the material editor and set the material ID to 2 .Then I highlight the poly's I want and assign them a material ID of 2 (the blue bodywork is ID 1).

Then I click 'Assign Material to Selection' and 'Show Map In Viewport' and it appears on the object right where I want it. But as you can probably see from the image above it's stretched out so much that you can only see one or two of the bars in the mesh.

I've tried adding a uvw map and setting it's map channel to 2 so that it should be able to scale up/down the texture but nothing I do when I try this method will affect the size of the texture what am i doing wrong here -I just don't get it. It's worked for me in the past when iu did a composite map (thanks again boy1da) but I just can't get my head around what I'm doing wrong here.

I'm sure i'm making a simple mistake but if anyone can point me the right way i'd love to hear from you.

Thanks, Mike

You can try UVunWrap . Go read up on it in 3D.max help

Go into you stack and switch offf the subselection in the editable poly after you have assigned your UVW-mapping.
Don't trust your viewport too much, render a test, if it is still distorted that bad, consider unwrapping.

Thanks for your help scrimski,

I got it sorted! I don't know how but after three and a half hours of fiddling it finally appeared correctly :)

However I don't know how I did it or what the problem was in the first place, so now I have a new problem with 'uvw map'..... :eek:

I'm trying to texture the inside of the door with an image of the real inside of the door. This is how I'm attempting it:

1/ I create a new bitmap texture using the door image as my bitmap

2/ I select the poly's I want to assign it to (all the square flat poly's of the inside of the door).

3/ Then I assign the material to the selection and the selection appears grey. So I think, 'ok I need to click -Show Map In Viewport- and that just makes it a different shade of grey. (see image below)

This happens whether I add the UVW Map before or after assigning the material to the selection. It also happens regardless of whether I have selected a new material slot or if I'm adding it as a material sub object in the slot I'm using for the other materials on the door.

I've tried rendering it out to see if the viewport is lying to me but it's grey rendered out too.

So I decided to do a quick test and made a cube in the same scene and applied the bitmap image to one of it's faces and it worked flawlessly. So I don't think there is anything fundamentally wrong with my Max settings.

I hope it's something simple and I'm just being a bit thick if any of you know what I'm doing wrong I'd be very grateful if you could let me know. :bounce:

I'm wondering if your getting confused with the use of Mat ID and Material Map Channels and UV map Map Channels?

so let me just check: (please dont take this the wrong way I'm just double checking)

All you need is for this to work is:
Polygon with UVs applied : check
Texture applied to polygon : check
Both the above using the same Map Channel (Not material ID, that doesn't matter for now)


What i see in your screenshot is UVmap with Map channel 7 and polygon material ID map 7 which makes no difference to it being displayed whats important here is the UV's on that set of Polygons must also be set to Map Channel 7.

I'll be happy to help as if this basic stuff doesn't fix it it could be one of the random Max things that happens.

Hi Blank thanks for your help,

I got it sussed! It was like this:

I'd applied the image to the polys but because they were selected I couldn't see that the image was there. i needed to hit f2 to make the selection visible and then I could colapse the uvwmap modifier and that was it - job done.
