Do you want to
[1]use the RA2 vehicle and have it deploy into the TS Conyard or do you want

But either way you have to extract the voxels and shp files from TS as well as the entries from the Art.ini put the voxels in a ecache*.mix and the shp's in a expand*.mix and you may have to rename them.

just add a 2 to the end, like gacnst2 then change the rules entry to DeploysInto=GACNST2 for choice #1

you obviously used the snow theater images and not the temperate ones.

You should also change the Foundation in art.ini to 3x3.

Well you learnt a bit about filenames, conversion, shps which is good but TS stuff is 25% smaller then RA2.

If you look at the selection box for the gancst, if anything attacks left of the box (where the hp bar is) i.e. empty grass, the structure will take dmg.

If you want a mod with expansion.mix

than put expansion.mix in your RA2 directory.

The file name is supposed to be named expansion**.mix or expansionmd**.mix. For RA2 and YR respectively. The ** can be anything, but most use a number. Something strange, like 57, which isn't used often.

In RA2 do moviesXX, mapsXX, expandXX, sidencXX, sidecXX, use the TS like enumeration with %02d
and elocal*, ecache*, movies*, maps* the RA2 string identification with * (movies and maps appear twice in the exe, one for each technique)

Do you have the correct voxel and HVA file?

In the rules, do you have an Image= tag pointing towards anything else then the art entry of your MCV (if there isn't an Image= tag, is your MCV named the same as its art entry and as its voxel and HVA file)?

Has the art entry of your MCV the same name as the voxel and HVA file of your MCV? That's all I can think of now.

expandmd##.mix
This is a type of mix file designed to overide things already existing in the game files. (as can be seen by rulesmd.ini in expandmd01.mix for Yuri's Revenge v1.001)
INIs
.TEM, .SNO, .URB, .UBN, .LUN, .DES
WAVs (EVA voices, not the audio normally stored in audio.bag)
SHPs (interface-/screen-elements, including side-related GUI ones)

ecache*.mix
As the name sugests, this is a cache file. The files in here are only read if they do not exist elsewhere, unlike other mix files where the last read file overides the previous versions files. the files inside these mix files are only indexed upon loading, and speculativly, the progressive number override doesn't apear to apply.
SHPs (normal buildings, infantry etc.)
.AUD files (Not used in Red Alert 2/Yuri's Revenge)
VXLs
HVAs
