Dear all, I would like to customize the transparency of a given mesh group. What I have tried so far is to modify the opacity of the mesh material, i.e. parameter “a” (one of the 4 RGBA colour components) which controls the opacity of a given material spec (diffusive, emissive, specular…) but...

Using oapiMeshMaterial function Hi BrainJ and all, Thanks for this, I have used the SetMeshMat() function within Mars Cargo Dragon code and it works just perfect! Now the thing is that when the engine ignites, the mesh colour changes immediately. I have been trying to change gradually the...

Thanks for your inputs BrianJ and Longjap. It's much appreciated!

Thanks Longjap, Thanks for that! I was aware of behaviour of the contrail due to the type of atmospheric and particle level function however I missed it completely here, my bad I should've seen that! Anyway I have tried it using the constant params as you suggested (LVL_FLAT and ATM_FLAT) and...

Hi BrianJ & Orbiters I am still trying to do some minor modifications on your fantastic FalconHeavy. I have started by changing things on the Falcon 9R v1.2 and have 4 questions. (I am not sure whether it would be more correct to ask each of the questions in different threads? Please let me...

Sorry guys, posted this in the wrong section. I'm moving it to add-on development and removing it from here

Hey guys sorry for the late reply, just wanted to let you know that the problem was a geometry issue. I need to redo some of the objects cause manipulateing the geometry was not fixing it but at least I know how to make it work. Thanks again to all of you for helping me out on this:thumbup:

Hi Orbiters, In case anyone have the same issue below is the link for the CMG CMG v2.0 Regards

Hi guys, Thanks to all of you for your replays! I will upload it somewhere and share the link with you when I get home I tried to flip normals and no changes... By the way, I noticed that GROUP SolarPanelB07 and SolarPanelB08 on DTV1012.msh (under .\Commercial Satellites Part...

Hi gattispilot, I can't see anything wrong on the log... Hi 4throck, could you please explain to me how flip normal vectors (is it the same as flipping visible side? I have tried that already...) using Orbiter Mesh Wizard, I could try that. Thanks!:thumbup:

Hi Orbiters, I designed a satellite (actually it was my wife who did the design:hotcool:) a while ago and noticed that some the groups within the mesh don't load any textures at all. When changing the texture in the mesh, you can only see a scale of greys changing but not the actual texture you...

Thanks BrianJ for your quick reply and for the brilliant FH add-on. Now it works;) I was thinking all the time that f9h_stg2 was the upper stage that’s why I didn’t even try to modify that one Thanks turtle91 for taking the time to explain to me how to set-up a project from scratch! I’ll now try...

Dear Orbiter-forumers I raised a question a few days ago about add-ons that can change the exhaust, contrail and smoke effects on existing vessels (see below) http://www.orbiter-forum.com/showthread.php?t=37487 I spent some time on orbithangar and have seen nothing so I decided to modify the...

Thanks fred18 for your reply! At the end I retrieved the values of the PARTICLESTREAMSPEC class from "mars cargo dragon add-on" (thanks to brianj for sharing the sdk) which implements the contrail effect that I was looking for and it worked! by the way using ATM_FLAT as you suggested;)...

Thnks for your reply boogabooga, I went indeed through all the parameters of the PARTICLESTREAMSPEC Struct Reference including the atmospheric params you mention. Unfortunatelly I didn't see any difference by tweaking those params :( My concern here is, why the exact same parameters work fine...

Hi there, I was wondering if any you know of any add-on that I could use to add some extra contrail and smoke effects on the FalconHeavy exhaust so as to get something similar to what you get with the Space Shuttle (see picture) FalconHeavy add-on -> FalconHeavy Thanks!:tiphat:

Hello there, I have trying to add some contrail effects to the main thruster of a satellite that I am currently building using Vinka's spacecraft3.dll but I can't make it work My last attempt has been trying to replicate the contrail effects used by Perseus add-on (Perseus Deep Space Ship)...
