1 ) TP Camera Collision
The camera does not move, mouse can only rotate camera up and down.
Character not visible behind models, camera does nothing.

There is important Navmesh functions to create advanced AI.

Many are already included in Detour Api, Skyline just needs to interface them to Lua.

findRandomPointAroundCircle

raycast

getCost

closestPointOnPolyBoundary

findPath

It’s a little better; but there is still notable rotation issues with navmesh when the character start a new destination.
Rotation stabilizes after some second, but rotation should be controled and smooth.

A rotation speed should also be available as Navmesh parameter to control how fast a character would turn.

You load a project the Asset Manager points to Skyline installation.

When you load an existing project, the Asset Manager should always point to the new project folder structure and location.

Navmesh needs a function telling if a destination is inside navmesh or not.
This can be used by AI to know if some destination can be reached.
It’s often used with AI and random movement, fleeing, wandering or other behaviours.

Box collision size can’t quickly be adjusted in the physics properties.
For example adding a box collision to a tree objects,the box is too big and can be adjusted in the editor.
It’s the same for other physics shapes.

It’s a great tool for optimization.

But when two models are merged , the resulting model doesn’t look like the two combined and the texture does not look the same.

And merged meshes doesn’t keep their relative offset when merged

How to reproduce the bug :
1) Under Light tools Change the sun light to a color.
2) Under render settings and ambient lighting, if you change Brightness it will reset the previous sun light color

Like most 3D engine, add a new object type that is directional light users can place, remove or control with script.
It makes possible having several directional lights active or activated individually.
And remove Sun light parameters under light tools or make it optional.

Lighting is scattered all around in Skyline, you discover some default parameters you must change are on Light tools for example you never got the idea it was here.

Those could be grouped on same window or same menu :
- Environment setup
- Sun light and Atmospheric hidden under light tools
- Post effects

Common post effects are missing to get better graphics.

-ACES tone mapping
-DOF
-color grading
-chromatic aberration

This is the lighting tweaking lot of time in Skyline

The new Navbot using navmesh example works when you click somewhere it goes to the position.

But when it turns it’s very buggy turning into all directions at same time and it stabilizes after some frames.

Navmesh API needs a function to allow us to setup the agent max turning speed.

Some characters could be heavy with lower turning speed.
It’s useful to tweak agent turning speed looking more natural and not too fast.

All features should be component based, actually Navmesh is a lua call , there is no component.

Skyline should get a nevmesh component.
There would be parameters exposed to component properties like acceleration , deceleration, distance min make navmesh stop, character radius if it could support avoidance.

Also some Lua functions would be needed :
- IsReachable for example, telling if destination position is inside navmesh
- Lua Access to the result array of navmesh calculation if users want to do something else with the calculated path.
- Lua Stop and resume functions , to be able to interrupt a path navigation and resume it if necessary.

GLFT2.0 is a modern format for modern rendering.

Some engines have open source import/export plugins.

It has some advantages over Collada or FBX formats :

GLTF is a JSON based format. It’s very easy to parse and the data already comes typed.
glTF allows specifying an external file for the big data, in binary format.
glTF’s file structure is crystal clear. No extra or redundant data exists. There is only one way the scene definition can be understood
glTF 2.0 fully supports skeletons and morph targets, which can be parsed easily and unambiguously.
It supports PBR based materials using the Disney/Unreal format, which is what most engines and 3D modelling applications use nowadays
It also handles two-sidedness and transparent materials, including alpha to coverage.
glTF 2.0 supports multiple animations per file,it also supports many key interpolation types, such as Catmull Rom and Cubic Spline.

glTF is developed by individuals from companies such as Microsoft, Unity, Google, Adobe, NVidia, Oculus, etc. in collaboration with Khronos.

Skyline does not have collision volumes objects without rigidbodies.

This is what is used to create hitboxes, collision zones, character or other objects composed of multiple collision parts.

Those collision volumes are used to have collision and detect collision against other objects or detect collision for raycast. Or to get ragdoll feature possible.

This is mostly used in games for characters , vehicles or any other dynamic entity.
Also used for static objects you want to create a simplified collision using some basic collision volumes.

Material sliders have sliders with big range values bigger than 1000.

It would be more accurate and better with slider range values be the same as shaders range values 0 to 1.

Adding sensor volume and trigger volume to some entity.
When they are removed, the properties keep some of their flags.

A good addition to skybox is to have an optionnal atmosphear scattering.

Reflection probes volumes baking for materials rendering.

Be able to add or delete reflection probes volumes per scene.

https://docs.unity3d.com/uploads/Main/RefProbeHandles.svg

Skyline will blend reflection probes volumes overlapping when rendering to avoid seems.

If no reflection probes are setup in the scene Skyline will fallback using a default scene skybox.

And have some parameters to tweaks, like resolution.

I exported a character from Blender as FBX, it has multiple animations actions recognized in Skyline.

When i try to play those on script, only the “WALK” animation works.

You can find the Blender, exported FBX and script test on zip below
https://ufile.io/kxno0

To test :
-drop the FBX character on a scene
-Add external script from ZIP to character
-Change script variableto : ANIMATION = “WALK”
-Play mode in editor, it works the character “walk” animation is playing.
-Change variable to ANIMATION = “IDLE” -The animation is not playing.

Like most engines be able to setup Physics constraints for movement and rotations on X,Y,Z axis.

Support for multiple collision volumes for characters, for hit boxes or weapons damage volumes.

Acutal Physix engine used by Skyline is v2.8.6.4 , it’s a ten years old version.
Skyline should update to latest version.
