• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Sketchup - Texturing Ground Vegetation?

I'm trying to make a simple grass model in Sketchup using 2 crossed polys. I have something I cant quite figure out how to do/fix that's slowing me down though.

This is what the grass should look like when displayed in FSX:

It may look fine in that image, but what I need to figure out is, how to properly texture the opposite side of the polys so that this doesn't happen:

I am able to add a texture by using the paint bucket to map the texture sheet I'm using, to the poly. But I cant figure out how to adjust it without messing up the correctly textured side.

This is what the model currently looks like in Sketchup with the now mapped backside in the picture following.

Whenever I right click and select Texture>Position it will mess up the front side so that its exactly the same as what the back now is. Is there any way around this?
 
SU follows the extremely standard convention of allowing exactly one each unique front face and back face for each polygon which cannot be changed, only reversed.

Click to expand...
The way around would be to texture only the front face and then make an identical model and orient it 180 degrees opposite. This will give you two properly textured front faces and two invisible back faces, I do not know if projecting the faces in opposite directions will have the same effect; because the faces are not in the same location, I imagine you might see some tearing or patterning as their planes approach angles of convergence in the same way ground poly's flicker - but it might work fine for you.
 
Hello:

AFAIK, Sketchup creates and uses 2-sided faces by default. ;)

Sketchup also allows independent use of the Front and Reverse faces of its objects, and each side of a face can be textured with either the same or different textures.


To prevent re-positioning the same texture first mapped to the front side of the planar object (since that texture was first projected and mapped to that front face in the model, thereby setting its "usage configuration" in Sketchup), one must select the texture on the reverse face, right-click, and choose "Make Unique Texture".

The texture which had already mapped to that reverse face as a 'copy' can then be independently positioned (since it is now handled by Sketchup as a different copy of the texture mapped to the front of the face).


BTW: If you have a texture mapped / sized / projected the way you need it for a front face, to apply that texture to other front faces directly adjacent to one already textured, with the Paint Bucket tool, hold down Alt (dropper appears) and click on the existing properly mapped / projected texture to copy the texture along with its "UVW mapping" attributes.

Then, immediately paint the desired other front faces directly adjacent to one already textured, and one can either display the continuing portion of the texture on that sheet, or individually position that copy of the texture mapped / sized / projected the way you need it for other contiguous front faces.


This may work for reverse faces as well; but after applying the texture mapped / sized / projected the way you need it for a front face, one must select the texture on the reverse face, right-click, and choose "Make Unique Texture".

The texture subsequently mapped to that reverse face as a 'copy' can then be independently positioned without affecting the source face location where the texture was copied from. :wizard:


Hope this helps ! :)

Gary, you are most likely correct. I havent used SU in a while and completely forgot about 'make unique texture'. That should work without making a new face.

Also, if you want to try for a more natural look, try making a few grass models in a random pattern
 
I assume the sun is shining in the direction of the second shot, making it lighter? If so, I don't think that's fixable for all times of day.
