• 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.

Minimize drawcalls: for selected texures only?

A question for you Arno:

When predicting/minimizing drawcalls is there a way to exclude some textures of the process?

The purpose is simple: imagine an object (a lighthouse, for instance ;) ) having some parts transparent (like glass of the lantern, or railings).
If I try to predict/minimize drawcalls, MCX does the job perfectly but transparent textures are then mixed on same maps together with solid parts.

How should I do to have railings and glass on a separate map? Is it even possible?

I'm glad someone else has mentioned this... if I recall this has been requested before ( by me ). It's on the wishlist, right Arno ? :)
 
You can export the transparent parts as a unique model, delete them and then minimize the draw calls for what remains; then you import you transparent parts with their own texture.
 
Hi,

As mentioned already it's not possible at the moment. And I also didn't find the change on my wishlist to be honest. But I can add it, should be relatively easy to skip textures with an alpha channel.
 
It would be very useful because more and more often imported models come from popular tools not very efficient at texture mapping (eg. Sketchup).
Thus plenty of texture parts, which would greatly benefit from your MCX drawcalls minimization tool.
But when alpha'ed textures are present, this is not possible (yet!)
 
The current approach where alpha textures are combined with the other textures does work. But it might not always be optimal since you will might get two sets of material parameters for the same texture.
