Dear Sir:Is there a way to create smal hills using the tmf tools and bglc?Can BGLC create bgl to the southern hemisphere?Thanks.Alfredo MEndiola LoyolaLima Peru

I've only made landclass updates with my Landclass Assistant proggie, but I thought Martin Wright had a program to aid in building mesh... Hopefully, someone can forward a link to you...-John

Hi Alfredo.BGLC is Microsoft's MASM assembly language compiler, that has been customized for Flight Simulator. It can create code for any region on earth.You can create hills with BGLC and Christian Stock's TMFmacros.incThe hills would be indexed to LOD13 areas, and would be TMF flatten code ( triangles at the least ) that can raise or lower the mesh. It won't appear flat, because the flatten points can be quite close together. It doesn't matter what the LOD of the underlying mesh is... the TMF flattens are LOD13. The advantage is the entire LOD13 area doesn't need to be meshed... just some flattens to create the hill.You'll need to download masm.zip and nzrc.zip by Christian Stock, from the Avsim Library. BGLC is contained in the Special Effects SDK for FS2002.You may also want to see georgio's fsregen for a Gmax-orientated solution for TMF flattens.

Hi Alfredo. Here's some code to create a small hill using Christian Stock's 'TMFmacros.inc', and BGLC:
