Welcome. They're pretty nifty. I click it every time one goes off

I haven't been getting them since your upgrade...

Are windows notifications coming back?

Not sure if this is a bug or I'm not using it right - should SetTorque() on a kinematic joint disable all rotation? I just want to position the joint and no matter what happens to it, have it never rotate. Here moving the joint makes it rotate all over the place.

Fixed culling bug, I think

Seems to be fixed in both examples and my larger project.

December 10, 2022

I threw together a quick example for you showing some of the issues I'm still seeing with entities popping in and out. The green cube pops in and out and in my other project so does the player cylinder, doesn't seem to happen here though. The entities are always in the centre of the camera and they still pop in and out. If you remove the player cylinder the blue cube seems to fine, it's just the cube attached the slider.

This has me extremely puzzled - I just started working with kinematic joints again, and all was good, I could set its position with SetPose() and other things, but then a few builds later CreateKinematicJoint() started returning nullptr for no reason same as the slider joint too. I uninstalled Ultra and reinstalled with no luck.

Here's an example project where 'k' is empty.

#include "UltraEngine.h"
#include "ComponentSystem.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    auto plugin = LoadPlugin("Plugins/LELegacy.dll");

    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a world
    auto world = CreateWorld();

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create a camera
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetFov(70);
    camera->SetPosition(0, 1, -3);

    //Create a light
    auto light = CreateBoxLight(world);
    light->SetRotation(35, 45, 0);
    light->SetRange(-10, 10);

    auto p = CreatePivot(world);
    auto k = CreateKinematicJoint(Vec3(0, 0, 0), p);



    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

Have you got physics shape visualization implemented yet?

December 9, 2022

I wonder if the backups for files that have been updated should be moved to a single folder in the project directory rather than having mountains of .bak's lurking about, especially in the shaders folder. It could keep the same hierarchy in the backups folder so you can find stuff. I take it Ultra is going to be heavily updated over the coming months / years so it could get out of hand pretty quick. Just a thought

EDIT : Or has is been done already..

I don't plan to support raw Basis files. KTX2 includes Basis compression and is a better format. All mentions of the Basis plugin should be removed from the documentation, although you can still use it if you want.

Are there any tools available to convert to KTX2? I can't seem to find any...

I ran the 3D GUI example in a new project and they still have the same problem I showed above.

Does GUI work in 3D?

I might want to check this out for myself as I was getting weird issues when making an in-game console a few months ago.

I have noticed with 3D GUI that the borders of the buttons don't line up, and on LoadGame I'm holding the mouse down and you can see the triangles that make up the background mesh. I think there are various issues like this with other widgets too. Haven't tested with a small fresh project though, if you'd like an example I can put one together for you tonight.

December 5, 2022

Is the Basis plugin meant to be missing?

December 5, 2022

The project is pretty big and it only happens like 1 in 20 times, I think even if I sent you the whole project you'd be trying for ages to actually make it happen.

December 4, 2022

This is going to be hard to pin point but randomly every few launches in debug mode it will crash with this error...

Stopping and restarting the debug session and it will then work. No idea how to solve it but thought it worth mentioning at least.

December 4, 2022

Not sure if this a bug, if I set a material to a model and then add a mesh to that model, the material is not assigned to the new mesh. You have to re-apply the material. Should it be so? I don't know...

December 3, 2022

Looks amazing now, good job 🙂

December 3, 2022

That's looks good. Is this an infinite water plane or will it work with any custom shape?

@Josh A lots changed since I've last compiled a custom shader - is this still possible? I get a few errors currently, I see Base.frag is now base_frag.glsl but I'm not sure if I should be suing that anymore...

December 2, 2022

Error: Failed to load shader module "Shaders/Downsample.frag.spv"

Most of the loading errors are gone - just have this one still.

I have been very good. They are called on the main thread.

November 29, 2022

If I create more threads than currently available, will the excess threads essentially wait for an available slot to execute in or do I have to manage this somehow?

EDIT : It appears to

November 28, 2022

Wow, with the new CreateMesh() arguments the largest patch can now be created 3x faster! Thankyou.

November 28, 2022

Would it be possible to remove a mesh from a model?

my_model->RemoveMesh(this_mesh)

Instead of deleting and remaking a model to remove the meshes it might save some time.

November 27, 2022

Might even be better again to create the new mesh instance and add it to a model as a different LOD mesh and let the shaders take care of LOD - is that how LOD works in Ultra? My only thoughts here are for a massive terrain over time the RAM and GPU memory could increase to large numbers (more so thinking GPU memory).

I could create the mesh on a separate thread and then assign it the model. If memory does become a problem I could create an entirely new model for patches that haven't been visited for a while or are so far away and then delete the old model with all the extra meshes.

Deleting a model will remove all the mesh information from the GPU and renderer?
