PLEASE HELP ! A BEGINNER TRYING TO UNDERSTAND TEXTURE MAPS

Postby kirklee14 » Wed Jan 29, 2020 12:07 am

I have been trying to pick up some rendering skills recently, the availability of different software and vast knowledge to consume are overwhelming. I did my research and needed some help from the experts to advise me on my current understanding of rendering software. Fundamentally, rendering software are mimicking reality by calculating light bounce between geometry and materials. Obviously, the more refined the geometry is, the more realistic it is. On the other hand, material are characterised by its layers of maps and information. Various type of maps such as diffuse, bump/normal, displacement map, ambient occlusion, reflection map etc. are used to achieve realism by providing material information within the rendering environment. The more layers of material map and information applied into the scene, the more realistic yet time consuming it is since more time is used to calculate the movement of light. Based on my understanding, Bump/Normal maps create an illusion of depth and texture but displacement maps actually deforms the geometry to create real depth and texture. Enscape supports bump map yet do not support displacement map, therefore, enscape is only capable of creating an illusionary depth of the material and not actually deforming the geometry. Thus, realism is flawed when the scene is perceive at a certain angle and perspective. However, Vray supports both bump/normal and displacement map, so its logical to say that vray can produce a higher quality image compared to enscape but has a higher learning curve due to its complexity. Each rendering software/plugin has its strength and weaknesses, thus, i should pick the most appropriate software depending on the context and my current skill cap.



Can any expert advise me regarding how true and correct my above statement is ? Thanks guys !

It truly is as they say "in the eye of the beholder".

Direct comparison, yes, Vray is more "powerful" than Enscape. But does that mean you get better renderings out of Vray than you would out of Enscape? Not necessarily.

It really is a subjective comparison, for example, in closer-up material rendering Displacement might be better for realism, but for most cases where the material is viewed at a distance you would be hard pressed to see a big difference between a displaced material or a bump'ed material.

More important than perhaps what software is being used to render is a) the quality of the materials and their maps and b) the quality of the model.

And finally, there is the Post-Process factor. I would say 80-90% of the "realistic" renders you see are 50% model, 25% render and then 25% post processing.

So to summarize, if you are just getting into rendering, I would look to start with a simple rendering engine to get the basics down. All these skills are transferable from software to software. If you get a 30 trial of vray you might spend 20 days just trying to get an understanding of all the settings whereas a 30 day trial of Podium or Enscape would have you up and running quicker.

Better yet, check out Twinmotion. Its a real-time rendered that is easy to use but you can work on materials the same way as you would with Vray and currently the 2019 edition is free.

Hope this helps,
Robert

Dear Robert, im currently studying architecture and i dont have the best computer and rendering skills. For now, i think i will stick with simpler software such as the ones you mention twinmotion/enscape and build up my skills from there on. Thanks for the explanation ! Have a great day!

...whatever tool you decide for - since you study architecture, focus on the essential things like materiality or lighting and don't let yourself be seduced by "nonsense" like trees blowing in the wind, like zombies walking people or stupid rippling waves in even stupider swimming pools and don´t waste your time with the photorealistic visualization of toilet bowls :D ;) unless, of all things, someone would pay a lot of money for it ;) ;)

:roflmao: :roflmao: :roflmao:
Its hard not to be seduced by moving images since its much cooler than 'static' ones. Yes, I will get my priorities right, zombie walking people and wind blowing trees are my last priorities. Thanks for the advice !
