[227i/j] Can't have multiple environment-mapped textures on a mesh (Read 596 times)

	Some models I've been porting from Half-Life have (in the original game) some reflective-looking surfaces, similar to the bMeshEnvironmentMap flag in Unreal. This flag seems not be taking effect when setting it in the meshes properties as seen below, where I've set bMeshEnvironmentMap to True for material groups 1, 2 and 3. The textures in this case for the Crossbow model are Gordon's glove, the crossbow lens and front section I've noticed that when using the mesh browser in 227j to set this flag, it seems to display correctly in software rendering, but the textures appear black when using OpenGL. Software: OpenGL: In game, the material groups with the bMeshEnviromentMap flag set appear to fall back to Engine.S_Weapon, regardless of the renderer I use. Changing the MultiSkins of the weapon doesn't seem to do anything either. Reproducible on 227i and the latest j build.

	By default Unreal Engine 1 forces all env-mapped textures to use Actor.Texture value. For 227 we added a variable to force it to use the assigned skin as env mapped texture: Actor.bRenderMultiEnviroMaps Change it to True for your weapon and it should be alright.

	Hey dots thanks for this, surprised I didn't notice it before! I did a quick test this morning before work so apologies if there's something else obvious I've missed. I've set this and it seems to work in Software mode (like in the mesh browser) Using OpenGL it shows black textures this time, as it did in the mesh browser view when using ogl there I'm at work atm but Ill check a few other things when I'm home Had no luck with any renderers other than software when I turn this option on for the weapons

	You may want to double-check your extended renderer options by opening the advanced options window in the View menu. I have had similar issues when OneXBlending, SinglePassDetail and UseMultiTexture are not set correctly.

I initially thought it was UseMultiTexture - seems however when UseHardwareClipping is set to False, it actually works!! Thanks for the pointers both Now to actually work on these...

	Yay, glad we got a solution, and something for Smirtsch to look into. I will also remember to change the clipping option next time I see it. Possibly it may allow more freedom with the other 3 switches. It is always worth using the advanced options window to tweak the renderer settings because they happen live and you see the changes, though sometimes in UEd you have to move the view a little to make it update.

Whilst flicking through the rendering options, I did have Unreal running windowed next to it so I could see the changes. Some changes did need me to go back to fullscreen to take effect which was confusing though! Smirftsch wrote on Jan 30^th, 2019 at 6:33am: Since this is a performance critical setting, what version are you on currently and what renderers are affected? This was using j_39 with Opengl. Seems it works as-is with no ini changes in software rendering and d3d8/9 at least. XOpengl shows black textures like Opengl did originally If it helps, UseHardwareClipping isn't an option in d3d or XOpengl and I didn't see any performance drop (AMD FX-8350, GTX 970, 8GB ram) Also minor bug report: When clicking "Reset to default" in OpenGL's advanced options, it didn't seem to reset UseHardwareClipping as it doesn't appear to be listed in default.ini under [OpenGLDrv.OpenGLRenderDevice] (Assuming that's how resetting it to default settings works)

	Hmm yeah the default.ini is missing lots of updated settings for new renderers. I create a new set of renderer defaults each time I update them or add a new 1. Bit of a pain but worth the convenience. Just delete the renderer section or just the contents of the renderer section in Unreal.ini, then access the advanced setings window from either the game or UEd and toggle 1 of the options in the changed renderer. This should write all the contents of the renderer ini lines at the default values (apart from the 1 you toggled, so toggle it back) Copy the new lines to the defaults file. Glad you reminded me Gizzy cough Smirftsch could we have a function added somewhere so we can generate new defaults easier ?

It's existing for D3D9/OpenGL and XOpenGL, so it should be tested in each. What it does is to batch single calls to one bigger call, so that instead of like 1000 calls of 1 Poly it's 1 call with 1000 Polys. This is mostly of advantage for rendering (static) meshes and makes a huge gain in performance in situations where these are used more often (or when using more complex meshes). This difference is even bigger in XOpenGL, because modern GL suffers even more from this "single call" behavior the UEngine1 is using, but even for the old rendevs it definitely makes a difference.

Indeed I made a complete new default setup for XOpenGL lately so that it checks and fills in all needed defaults if not there, but for the others I think it should be easiest to plain update Default.ini accordingly.

	@Smirf, sent you a PM This was tested in j_39. Works in D3d9, regardless of UseHWClipping setting Only works in OpenGL & XOpenGL when UseHWClipping = False (Black textures otherwise) As for the default setting not setting properly, modifying default.ini like the below should fix that: Code [OpenGLDrv.OpenGLRenderDevice] ... ... UseHardwareClipping=True Dr.Flay™ wrote on Jan 31^st, 2019 at 12:58am: cough Smirftsch could we have a function added somewhere so we can generate new defaults easier ? You can click "Reset to default" in the advanced properties window, simple enough I think If there's other defaults missing as you mentioned, it might be handy to post them here so smirf can update default.ini
