[CreateTerrain Assert Error]

The error now reads "Failed to make texture 9 bindless.  Format: 139"

Only took 19 seconds to get the error rather than 5 minutes so that's good.

[CreateTerrain Assert Error]

I got an error!  I waited 5 minutes and finally got an error.  "Failed to make texture 9 bindless."

Call Stack:

[CreateTerrain Assert Error]

I waited 2 minutes but it still hangs at the same place.  Call stack is the same as I posted above.  Project is up to date and cleaned.

[CreateTerrain Assert Error]

It still hangs in the same place.  Project is up to date.  This is the call stack when I pause it after a minute or so.

[CreateTerrain Assert Error]

Will test very soon.  I just woke up.  🥱

[CreateTerrain Assert Error]

Maybe a remote debug then?

[CreateTerrain Assert Error]

A different error but it might help pinpoint this problem... just simply creating the terrain crashes to "encodeData" or something like that.

[CreateTerrain Assert Error]

Um... well the errors gone but I think it's now stuck in a loop or something... currently at 3 minutes at time of posting.

[CreateTerrain Assert Error]

It says it does.  I have had other shaders of mine compiling and running that use that extension.

[CreateTerrain Assert Error]

Kind of.  This is the call stack.

...did you say that terrain textures need to be the same size as the terrain resolution?

I see the extra parameter for the texture size.

[CreateTerrain Assert Error]

GTX 980 Ti.  I'm seeing if there's a driver update now.

[CreateTerrain Assert Error]

Could it be problem with Refraction.fx or might it be totally unrelated?

[CreateTerrain Assert Error]

Downloaded the latest update and updated the project and still the same error.  Do you get this error on your machine or is it specific to my machine you think?

[CreateTerrain Assert Error]

Yeah that's the only error I got.

[Ray-Casting a Heightmap for Shadows]

Got it back down to about 200ms by increasing ray step size based on how high the ray is above the terrain at that time.  I have another idea that could decrease the amount of rays that actually need casting by up to 50%.

[Ray-Casting a Heightmap for Shadows]

Did this and it seems to work nice.

if (enable_lighting == true && (RenderFlags & RENDERFLAGS_NO_LIGHTING) == 0)

Only issue left to solve are the edges of the shadows are very harsh.  If I can use a single bit as a Boolean to disable lighting I may also be able to use a few bits to determine the distance from the light source so that I can soften the edges.  

[Ray-Casting a Heightmap for Shadows]

This iteration is a bit slower but looks a lot nicer.  The shadows are just multiplied by the final color so fragments within the shadow are still having light calculated on them.  @Josh Can I make a bool variable in the fragment shader to simply not calculate lighting for certain pixels?

Something like this perhaps?  EDIT : There's a RENDERFLAGS_NO_LIGHTING right there.... I might play with that 

if(canDoLighting == true) {
    if ((RenderFlags & RENDERFLAGS_NO_LIGHTING) == 0)
    {
        RenderLighting(material, materialInfo, vertexWorldPosition.xyz, n, v, NdotV, f_diffuse, f_specular, renderprobes, ibldiffuse, iblspecular);
        if (!renderprobes)
        {
            ibldiffuse = vec4(0.0f);
            iblspecular = vec4(0.0f);
            f_specular = vec3(0.0);// we don't want specular reflection in probe renders since it is view-dependent
        }
    }
    else
    {
        renderprobes = false;
        f_diffuse.rgb = materialInfo.c_diff * AmbientLight;
        f_specular = vec3(0.0f);// we don't want specular reflection in probe renders since it is view-dependent
    }
}

[Loading custom model format throws error]

This file causes LoadModel() to hang rather than crash.  Is there some sort of secret header that all model files should have? 

To confirm - this is not with any plugin I've made, this is just loading a file that doesn't have much data and is in a format that LoadModel() doesn't recognise.

I've also seen LoadModel hang and rapidly increase RAM usage into the tens of GB.

The example here throws an error with the latest build.

[TEXTURE_RED missing]

Has TEXTURE_RED been replaced / missing or is it redundant now?

[Failed to compile shader PBR_Masked.frag]

Got this error with one of the shaders in latest update.  I did copy the shader folder over to my project.  Adding in the required line solves the problem.

[Merging Animations]

As discussed bender has some issues with converting FBX to GLTF.  What would be nice is to have a feature in the Model Editor that allows us to add the animations from another model onto the current model.

Mixamo (as far as I know) only exports one animation per FBX file.  SO using that means we could have a few dozen models of the same thing with different animations.  Currently the only way to merge them is through blender or some other software. 

[Asset editor won't save animation]

After some discussion with @Andy90 there is another problem that I'm not sure has been raised yet... so here it is.

This FBX has been exported from Mixamo.

If you drag it into a folder in the editor it will convert perfectly.

If you open the GLTF in the asset editor the animation is present and working, however if you then save the model from the asset editor you get a notification that says it has "animations that won't be saved".

So you can only save the model if you don't want to keep the animation.

[Loading custom model format throws error]

This is 0.9.4 by the way...

Happens in 0.9.5 too.

[Loading custom model format throws error]

I was creating the file with a buffer but changed to WriteFile but it still throws an error in LoadModel and crashes the application.  This is how I'm creating the model file.

void SaveModel(WString filepath, shared_ptr<Model> model) {

    auto version = 1;
    auto file = WriteFile(filepath);
    auto total_lods = model->lods.size();

    file->WriteInt(version);
    file->WriteInt(total_lods);
    for (auto lod_index = 0; lod_index < total_lods; lod_index++) {

        auto total_meshes = model->lods[lod_index]->meshes.size();
        file->WriteInt(total_meshes);

        for (auto mesh_index = 0; mesh_index < total_meshes; mesh_index++) {
            auto mesh = model->lods[lod_index]->meshes[mesh_index];
            auto total_vertices = mesh->CountVertices();
            auto total_indices = mesh->CountPrimitives();

            //Save Vertices
            file->WriteInt(total_vertices);
            for (auto vert_index = 0; vert_index < total_vertices; vert_index++) {
                auto vertex_position = mesh->GetVertexPosition(vert_index);
                auto vertex_normal = mesh->GetVertexNormal(vert_index);
                auto vertex_texcoords = mesh->GetVertexTexCoords(vert_index);

                file->WriteFloat(vertex_position.x);
                file->WriteFloat(vertex_position.y);
                file->WriteFloat(vertex_position.z);

                file->WriteFloat(vertex_normal.x);
                file->WriteFloat(vertex_normal.y);
                file->WriteFloat(vertex_normal.z);

                file->WriteFloat(vertex_texcoords.x);
                file->WriteFloat(vertex_texcoords.y);
            }

            //Save Indices
            file->WriteInt(total_indices);
            for (auto indice_index = 0; indice_index < total_indices; indice_index++) {
                auto v0 = mesh->GetPrimitiveVertex(indice_index, 0);
                auto v1 = mesh->GetPrimitiveVertex(indice_index, 1);
                auto v2 = mesh->GetPrimitiveVertex(indice_index, 2);

                file->WriteInt(v0);
                file->WriteInt(v1);
                file->WriteInt(v2);
            }
        }
    }

    file->Close();
