Mirrors don't reflect 100% of light, they just reflect light accurately. Learnt that from a video about a material that reflects nearly 100% of light, but still doesn't look like a mirror.

All surfaces reflect light accurately. Reality doesn't mess up calculations.

@@coreyaruecker "accurate" here means accuracy such as in archery, meaning moving in the same direction as the other photons reflecting against the surface.

For add for some people who wasn't sure what was a height map, In 3D term the height map is also call a displacement map in most 3D modelling software which why it's more memory intensive is because it's takes the current model vertices and move them along the displacement map. Although the less vertices you have the less the result will be accurrate :)

@hoiblij6737 6 лет назад

Nio Kasgami English

@n__m 6 лет назад

in this case the height map is used for parallax mapping, not displacement or tesselation. you can tell this from the fact that the profile of the geometric object stays consistent when height maps are being used.

@Fabian-_- 6 лет назад

I kinda know what you would answer, but which Engine is better? UE4 or Unity? Based on these: - how simple it is (Ui etc) - most assets (FREE) (real or low poly) - best customization (like in Unity the start screen only can be changed with Pro) - best terrain generation (also procedural) - best AI/KI player - best export (most important: export to Linux, cause I use and love it) - best support for OS (Editor) (which one works better on Linux? Unreal you would have to compile yourself, Unity has a Linux Client) - best tutorials and help (I would say Unity, but only cause I'm newer to UE4 than to Unity) - most realistic (UE4, but Unity isn't bad too. Just a bit harder to make it look real, UE4 is built for this, right? - multiplayer support - Multi Edit (so you can build the game with your friends or colleagues) Thanks for everyone who helps me with my decision :D

@SnyppiTV 6 лет назад

Both are great engines. What type of games do you want to make?

@Fabian-_- 6 лет назад

The Brown Cat most I think I'll do FPS or Story games. Lowpoly or realistic, but if real then as real as possible (with free assets)

@SnyppiTV 6 лет назад

Fabian well both have great free assets. Do you know how to code?

@Fabian-_- 6 лет назад

The Brown Cat yea, C# and c++ a bit, but I want to learn them anyway... Need more programming languages xD I know, you wanna say UE4 cause visual scripting, but I kinda get confused with this. So I may prefer coding

One thing: I think your drawing of Diffuse lighting is really what Subsurface Scattaring is. Diffuse is simply randomized reflection off of a rough surface. You graphic showed light rays going under the surface and bouncing outwards again - that is Subsurface Scattering, not Diffuse.

@isays 2 года назад

came to the comments to say the same thing. diffuse reflection still a surface reflection, just not specular.

For the metalic slider, to do it PBR correct it should be either 0 or 1, nothing in between.

@Samota0 6 лет назад

There are some Dielectric materials that actually require the usage of values in-between 0 and 1 actually.

@MatheusLB2009 6 лет назад

Thats where youre wrong, kiddo. No material in real life reflects 0 or 100% of light. If it did, metallic maps would be either completely blank or dark. That said, if you think a value of 1 looks better, go with it

@AndyBakerUK 6 лет назад

How about metallic resins?

@PiesliceProductions 6 лет назад

LumenLumen yeah you are correct. also the term metallic is a bit misleading, as it is more like material`s abilith to *conduct* light. also many dielectrics (insulators) have conductive properties, such as water or gem stones. the difference between conductor and dielectric is that the reflected light`s spectrum varies only little on dielectrics, but conductors can change it a lot (gold and copper)

@NagyerdeiKorisok 6 лет назад

Hi Brackeys. Do you have some recommendation on the size of the textures? I've read that having large images on big faces aren't as optimal as subdividing the face into smaller segments and have tiled texture. But where is that optimal level and what resolution should my textures have?

@MatheusLB2009 6 лет назад

Uristenzor - Nagyerdei Korisok Bigger resolutions look better but take more size on Ram and Hd. You should test them and do changes when needed. You can also change the UV maps, to make some parts take a smaller amount of texture and others take bigger

@michaelvolpa7771 6 лет назад

If it’s a high quality asset or huge a 2k texture. 1k or lower should get most jobs done though.

@England91 6 лет назад

Uristenzor - Nagyerdei Korisok could just bake the high poly onto the low poly to fake it. If you don't know how look up the RU-vidr Blender Guru

@thebelugaking 6 лет назад

@Pelitaiteilija 6 лет назад

While I like the video, I have to disagree a bit on your definition! It's a pet peeve of mine. In classical rendering, it's easy to make mistakes that break energy conservation, or ignore Fresnel, etc. It is, of course, a cheat - but so is PBR. PBR does solve all of the problems you mentioned, and it is a great improvement, but the classical rendering models (diffuse / specular maps etc) are also based on observed or measured properties of light, reflection, etc. I think the important difference is that the classical shading models try to define and approximate individual properties of light and reflection (e.g. ambient, diffuse and specular) separately before they're combined, while the various PBR models approximate properties of the material and use those to calculate all the included forms of light and reflection in one go.
