0.9.6 Fixed bug in editor where animated models would not appear the first frame, in the first viewport. All directional light shadow cascades now render each frame in editor. Fixed some glitches in the outline post effect.

Have you installed Nvidia's current driver?

Hi, I just tried the following with a GEForce 1080 and the latest driver 552.12. Deleted the file "C:\ProgramData\Ultra Engine\settings.json" to reset all settings. Launched Ultra Engine Pro on Steam, default branch (0.9.5) Created a new project. Opened the Visual Studio solution and compiled for debug and release. Ran the game, and the start.map game opened and ran. Questions: Are you launching from the editor or from Visual Studio? If you are in the editor, do you have the start.map scene open in the editor when you launch? This is a new project, right, not an old project that was previously created with the Vulkan build of Ultra? It sounds like maybe the program is not loading the starting map, so there is no camera and just a black screen.

The Ultra string classes are not exposed in Lua. Ultra uses wide strings, which do not work well with Lua strings. However, all command interfaces between C++ and Lua that pass strings convert UTF8 (Lua) to wide strings (C++) and back. I have added the string methods as functions that can be used like this: s = "test" s = Right(s, 1) s = Trim(s) I also added Len(s), which is like Ultra's GetSize() method for the string class. This will be available in the next build.

I tried these in the editor console and they worked.

Fixed for next build, tested in editor console.

Another small change I forgot to mention is that if the create object button in the toolbar is already selected and you click it again, it will open the object selection window. It's subtle, but improves the flow of the program.

0.9.6 Added "Load LOD" menu item in asset editor window.

0.9.6 Asset editor will now save colliders embedded in an Ultra model file instead of as a separate file. Asset editor now displays all materials a model uses, including external material files. Added "Appearance" settings group in asset editor limb properties. Added LOD distance setting in asset editor limb properties. Model::SetLodDistance parameters changed, up to four LODs are supported. Added World:GetEntitites to Lua API

I am looking into it. In the meantime, version 0.9.4 is available to choose from in the application settings in Steam.

Here is how colliders are stored. For tolerance and optimization, if you don't know just write 0.0 / 0: // Collider if (stream->ReadString(4) != "PHYS") { auto pos = stream->GetPosition() - 4; Print("Error: Expected PHYS tag at position " + String(pos)); return false; } int colliderdatasize = stream->ReadInt(); auto colliderstartposition = stream->GetPosition(); if (colliderdatasize) { Vec3 position, scale, euler; Quat rotation; std::vector<shared_ptr<Collider> > parts; int partcount = stream->ReadInt(); for (int n = 0; n < partcount; ++n) { if (stream->ReadString(4) != "PART") { auto pos = stream->GetPosition() - 4; Print("Error: Expected PART tag at position " + String(pos)); return false; } shared_ptr<Collider> part; auto tag = stream->ReadString(4); if (tag == "HULL") { float tol = stream->ReadFloat();// tolerance std::vector<Vec3> points; Vec3 p; int count = stream->ReadInt(); for (int n = 0; n < count; ++n) { p.x = stream->ReadFloat(); p.y = stream->ReadFloat(); p.z = stream->ReadFloat(); points.push_back(p); } part = CreateConvexHullCollider(points); part->tolerance = tol; } else if (tag == "MESH") { int opt = stream->ReadInt();// optimize flag int count = stream->ReadInt(); int vcount; std::vector<Vec3> face; Vec3 p; std::vector<std::vector<Vec3> > meshfaces; for (int n = 0; n < count; ++n) { vcount = stream->ReadInt(); face.clear(); for (int v = 0; v < vcount; ++v) { p.x = stream->ReadFloat(); p.y = stream->ReadFloat(); p.z = stream->ReadFloat(); face.push_back(p); } meshfaces.push_back(face); } part = CreateMeshCollider(meshfaces); part->optimizemesh = opt; } else { position.x = stream->ReadFloat(); position.y = stream->ReadFloat(); position.z = stream->ReadFloat(); rotation.x = stream->ReadFloat(); rotation.y = stream->ReadFloat(); rotation.z = stream->ReadFloat(); rotation.w = stream->ReadFloat(); scale.x = stream->ReadFloat(); scale.y = stream->ReadFloat(); scale.z = stream->ReadFloat(); if (tag == "BOX_") { part = CreateBoxCollider(scale, position, rotation.Euler()); } else if (tag == "CYLI") { part = CreateCylinderCollider(scale.x, scale.y, position, rotation.Euler()); } else if (tag == "CONE") { part = CreateConeCollider(scale.x, scale.y, position, rotation.Euler()); } else if (tag == "CCYL") { part = CreateChamferCylinderCollider(scale.x, scale.y, position, rotation.Euler()); } else if (tag == "CAPS") { part = CreateCapsuleCollider(scale.x, scale.y, position, rotation.Euler()); } else if (tag == "SPHE") { part = CreateSphereCollider(scale.x, position); } else { Print("Error: Unknown collider type \"" + tag + "\""); return false; } } if (part) parts.push_back(part); } if (parts.size()) { if (parts.size() == 1) { model->SetCollider(parts[0]); } else { auto c = CreateCompoundCollider(parts); model->SetCollider(c); } } stream->Seek(colliderstartposition + colliderdatasize); }

This could be used to auto-generate LODs for a model: https://github.com/melax/sandbox/blob/master/bunnylod/progmesh.cpp

Yes.

Bone rotations are quaternions in local space (relative to the parent).

What version does the editor show in the titlebar?

Sun properties have been moved into a new dialog, available with the Edit > World Settings menu.

What version of the editor are you using? The version number appears in the title bar.

Please upload your project so that we can try it out.

It will be binary, although I have not added it yet.

The physics properties in Blender have some rigid body shapes that map closely to Newton. Might be interesting to you:

I just ran this in the console with no errors:

0.9.6 First build of 0.9.6 available on beta branch, adds saving to the asset editor for the new version of our model format. Embedded materials are saved as external files. They still get displayed the same way in the asset editor as embedded materials, and when you save the model it resaves the material files, so any changes you made will go into those files. This works out nicely.

Here is my loading code. I think this is final. A new section was added for node attachments to bones ("ATCH"): G3DModelLoader.cpp
