Mesh-clinging Water using Christian Stock's TMFmacros

[rhumbaflappy 113]

Hi all.If hand-coding TMF water for BGLC compilation, or using FSRegen to create the code, all water is flattened.I was asked if Christian's TMFmacros.inc could be used to create mesh-clinging water... Yes, it can:

This code will work in CFS2 as well as FS2002.

Could you maybe post the code for putting a decal over the default airport layout polygon/decal thing? I do not understand all this code, so a dumb user explanation would help. I have the Ryan's Creek scenery and have read (tried to) the design stuff, but I lack so much knowledge in hand coding that it doesn't make much sense. I would like to replace the default airport decal at KRDU with one of my own or something better.Thanks in advance!

Hi tlassiter.I noticed in another post you stated you were comfortable with GMAX, and familiar with fsregen.Your best bet is to go to George Ioannu's fsregen site ( ). georgio has done a great job with this so far. You'll need to download 0.029ctest version. His html covers the creation of water, and links to a short tutorial on creating decals. I could do no better for you. The link for [link:www.nhreas.com/fsregendocs/decals.html]Creating decals describes a process of placing a slightly larger decal under a TMF pond, in order to create a type of shoreline. ( TMF water always overlies decals... that's how coastlines are made over the rough landclass tiles, and why LC tiles must extend into the ocean a ways ). But the decal process is the same for laying down an airport background, or altering a small section of a landclass tile, or faking a road ( with a skinny polygon ). At this point, I suggest you use George's fsregen along with Gmax, as it avoids the BGLC hand-coding. I hand code with my experiments, but I usually use George's tool to properly locate the LOD8 Group and LOD13 offsets. As far as covering an airport background goes, you can slew over the area you want to change. Use a top-down view and Shift-z to get to coordinates. Use those coordinates with Gmax and fsregen to create the decal. The Scenery library order will place the decal's BGL on top of the ABP*.bgl ( airport background polygon ). The runway ( and any TMF water or lines ) will automatically lie over the decal.

Here's what I'm taking about:First, it's Ryan's Creek, by Christian Stock.Then, it's the same scenery, but I made a new ABP decal, and placed it in it's own scenery folder structure. This new decal overrides the Ryan's Creek NZRC_ABP.bgl, as the Scenery Library places the new scenery after the Ryan's Creek default:
