Unwrapping problem
show user profile  sheheryar_noor
Hi guys i been following a tutorial of light mapping for Unity using Vray . I am posting all the pics what i have been doing
1.

Simple plane with a diffuse and bump map. Map channel is set to 1 here.
2.
Applied UVW Map modifier. Map Channel is set to 1 according to tutorial, pressed fit and then manipulate
3.
Applied Unwrap UVW, Map Channel set to 2 (Unity use Map Channel 2) and that's what was in the tutorial.
4.
Selected face
5.
Flatten Map
6.
Use Existing channel>Channel =2, and add VrayCompleteLightMapping.
7.
After pressing render i face this error but when i check the Renders to file only then i don't face this error" The following elements do not specify a target map slot:

8.

And the last image, when i put that image in unity the black part which i high lighted in the last pic shows in unity.

Now its your turns guys to help me out :D

I didn't see a question...

You get the expected results...Your channel 2 bake matches your channel 2 UV.
If you wanna get rid of the black bit in the map you need your ground plane to be square, or stretch the uvs to fit the entire uv space.

The map channel in the first image only applies to the BRDF parameters...ignore that. You get the correct result because the default uv channel is map1, and it can be found inside the diffuse options where your texture is loaded.

In thise case its just a plane so UV1 and 2 can be identical...just copy one to the other.

Basically, make the face in Step .5 look like the face in Step .4.

Go to vertex level and snap the top two verts into the corners.

So if i want to get rid off the black part i need to stretch the face to fix it in square?. The question was if i was doing fine and why do i get the black part in Final image which shows in unity too, and one of my another question is about the error" The following elements do not specify a target map slot"is it because of not checking "Renders To files only?" After pressing flatten map which reduce the face in editor, so if i stretch it back to the corner then what was the purpose of flattening it?Else i am doing correct?

"After pressing flatten map which reduce the face in editor, so if i stretch it back to the corner then what was the purpose of flattening it"

It shouldn't matter, all I can think of is Unity is overriding the UVW's somehow, if it looks good in Max viewport then it should look the same in Unity unless something has gone screwy in the export process.
Try editing the UV's in Unity.


edit:

"The following elements do not specify a target map slot"is it because of not checking "Renders To files only?"

It means you haven't specified a target map slot, these are basic unwrapping procedures all covered in the Max help file ;)
