These are the logic components planned to ship with the planned FPS template. These are still considered a work in progress and subject to change. At this time, there's no Lua variants. These components and more will be documented and have examples in the future. Feel free to report any issues or suggestions! Logic.zip

That's how normal maps should look. The yellowing is due to BC5 compression. All normals should look like that as a game texture.

You need to generate the mipmaps and the compression needs to be BC5. Replace the bottom with this. auto dest = CreatePixmap(src->size.x, src->size.y, src->format); SobelFilter((uint8_t*)dest->pixels->Data(), (uint8_t*)src->pixels->Data(), src->size.x, src->size.y, 32); //dest->Save(StripExt(filePath) + "_normal.dds"); //Build mipmap chain auto mipchain = dest->BuildMipchain(); auto ddsformat = TEXTURE_BC5; auto blocksize = 4; auto count = mipchain.size(); auto block = dest->blocksize; if (ddsformat != 0) { std::vector<shared_ptr<Pixmap>> mipchain2; for (int i = 0; i < count; i++) { if (mipchain[i]->size.x < blocksize or mipchain[i]->size.y < blocksize) break; else { mipchain2.push_back(mipchain[i]->Convert(ddsformat)); if (mipchain2[i] == NULL) { Print("Error: Failed to convert \"" + path + "\" to format " + String(ddsformat)); } } } mipchain = mipchain2; } SaveTexture(StripExt(filePath) + "_normal.dds", TEXTURE_2D, mipchain);

That seems to fix it for the most part, but the concrete wall is still not the same unless I change the roughness down to 0.989. I'm noticing some flickering with what I've sent.

DM sent.

It seems with the new beta, the light doesn't affect materials like it used to. 0.9.8b 0.9.8

This demo shows projection issues in 0.9.8. VRTest.7z

I brought this up with you last week and you've told me that it has to do with e scene loading code, and render layers, but it still isn't fixed. So I'm making this a bug report as a gentle reminder.

I think a better option is to save out the calculation in a binary file and be able to load them instead of having them in memory at all times.

I would pay $20.21! Great deal!

This extension is for those who have existing materials that were made for the Blinn-Phong shading (diffuse+normal+specular) such as the textures for Leadwerks. Right click on an image with a specular suffix in the name and a "Convert Specular to Metal-Roughness" option will show up. This will take the spec sheet, insert the existing pixels in the blue channel, then swap the pixels and store that copy into the green channel. (This seems to take a bit) The result will be a blue and green texture. In your material, you then can use the Metalness and Roughness spinners to adjust the values. I find setting the Metalness to 0.1 is what you want for most non-metal textures to mimic the specular effect. For things that are metal, well that's up to you to tweak and find out. It really helps if you know how the material should look. The only thing you might need to consider is any roughness map you've made if you came from Leadwerks. That mask wasn't really conventional, and you may want to look into packing that yourself with the Channel Packing Tool to get the desired look. SpecMapToMetalRoughness.lua

I am now running into this issue in my map where the models don't render on map load unless I first highlight them. This is the start map in the XFORM project.

"environment": { "ambientlight": [ 0.0, 0.0, 0.0 ], "diffusereflection": { "path": "Materials/Environment/Default/diffuse.dds" }, "effects": [ { "path": "C:/Users/username/Documents/GitHub/XFORM/Effects/SSAO.fx" }, { "path": "C:/Users/username/Documents/GitHub/XFORM/Effects/Bloom.fx" } ], If you ship the game, post effects will be broken since the developer's hard path is saved,

You can retrieve the framebuffer from the active window.

Now it happens in Debug!

Build and launch the release build of XFORM.

A "Change/Load Theme" option would be nice. Also, Here's how my old "Midnight" theme looks.

There should be a simpler way to do this!

Dumb question but are you using the VRPlayer component?

I've had this happen to me and it looks like you beat me to reporting this.

I was working on a catapult trigger last week and it wasn't working for some reason. Made a new test component and seemed to work ok. I'll mark this as "solved" for right now but if I have any issues, I'll be sure to let you know.

The properties highlighted don't seem to get saved, Friction is written, but never updated to reflect the fields. There are no Damping, gravity, elasticity nor buoyancy values! { "castshadows": true, "collisiontype": 1, "components": {}, "decallayers": 1, "extras": {}, "friction": [ 0.5, 0.8999999761581421 ], "group": "2344763719232", "mass": 5.0, "matrix": [ "0x3f6803ca", "0x0", "0xbed86168", "0x0", "0x0", "0x3f800000", "0x0", "0x0", "0x3ed86168", "0x0", "0x3f6803ca", "0x0", "0x411c28f6", "0x3ef5c278", "0x40ccccce", "0x3f800000" ], "model": { "islimb": false, "path": "Models/ExampleContent/WeightedBox.mdl" }, "name": "weightedbox", "physicsmode": 1, "pickmode": 1, "position": [ "0x411c28f6", "0x3ef5c278", "0x40ccccce" ], "quaternion": [ "0x80000000", "0xbe5da255", "0x80000000", "0x3f79ee89" ], "reflection": true, "rotation": [ "0x80000000", "0x41c7fffd", "0x0" ], "scale": [ "0x3f800000", "0x3f800000", "0x3f800000" ], "uuid": "5cf9e831-0f12-404b-bc87-50c8f490ac79" },

The target property doesn't get in the map file when assigned. If you replace this with a normal string field and manually enter the uuid, the code will work fine. You can step through this. component.zip
