Hi All,
we are all often concerned to achieve more and more detailed and realistic renderings. Despite of this I often need to present my architectural drawings/images just like mockups or monochromatic illustrations. This because in the early stage of design a certain abstract level of representation is required or simply because the image content doesn't require to be photorealistic. I'd like to share with you ideas/opinions/works about HOW TO achieve best results which in this case from my point of view means fastest rendering with very simple scene setting-up. Finally, my question is, How to properly ILLUSTRATE with our best loved rendering engine Vray? This could sound just like an odd question or a misuse of 3dsmax which is mainly used for photo-realism. Regardless of this standpoints, I claim "conceptual" renderings can be as fascinating as best photo-realistic ones are.
Here three tests I did comparing lighting and settings with time. For all the models I used IRR (MEDIUM)+QMC , ADAPTIVE Image Sampler. The three main images are 320x240, Material Color is GREY 111, The plane has some blurry reflection.
First I tried with what is supposed to be the best way to get such kind of rendering.
1) INDIRECT ILLUMINATION+Environment override
Pros
Very quick set-up
Overall good mood
Fastest rendering
Cons
Depending on the model illustrated may lack of details. The image shows surface and edge flattening due to absence of a real light.
PS
Note how in the second image I moved away just a little the ground plane to get the shadow at the intersection point.
2) HDRI ILLUMINATION
Pros
Clear results in terms of edges and colors.
Good overall light conditions
Very easy setting-up
Cons
Rendering time increases relating to model size
Depending on your hdr image, light and atmosphere may be unpredictable.
3) ENVIRONMENT+Vray Light (usually rectangular)
Pros
Clear and sharp result
Convenient time
Cons
Depending on your model you may need light and material color tests
Two More image I did.
VRAY SUN+SKY
HDRI
So I can conclude that for simple scene/model I recommend GI+Environment override. For more complex models HDRI or rectangular light maybe preferred.
What's your experience/work about this topic? Do you know any way to produce sharper image just with GI+Environment override even with detailed models?
ENVIRONMENT LIGHTING ISSUE
As you can see this lighting method produce very smooth image which is a failure when you don get clear edges and incorrect surface shading. It seems the light does come just behind the viewpoint/camera perpendicular to the view window. This may cause a flattening over the objects close to the view. Do you know any way to avoid this?
