[Max] I need help! / Looking for help :)!

« on: 2022-06-26, 10:10:36 »

Hey guys, hope you all doing well,,
actually during my architecture work, i have been always wishing to master visualization, or making photo-realsitic renders,
anyway, months ago, i forced my self to change my workflow in sometimes to work on 3ds max and using corona render as a render engine,,
but i notice some points that i am really seeking to find solutions for,
1- i have lack of knowledge in materials and its parameters! or lets say i find it difficult to understand how sort of things work!
2- I am using revit most of the time, My model lines lack realism, and feels if it's rigid lines!
3- Mastering lighting!

- -
So is there any way to figure out 3ds max building materials and its parameters easily!
and how to improve my model lines before i import them to 3ds max, same thing for lighting.


greetings.

1. Is it a nighttime or daytime scene? The building is too bright and the sky is too dark for it to be either.
2. Why is there a Porsche and a Lamborghini parked outside what looks like a moderately priced hotel, in an open-air parking lot? I doubt owners of high-end sports cars would 1. park their cars outside 2. be at a place like this in the first place.
3. car materials need improvement; rear lights, tires, rims
4. parking lines are too uniform; they should appear faded, dirty, etc.
5. foliage is fine(?) but colors are too dark, too saturated
6. UV mapping on curb is broken
7. curb is low poly
8. wood is flat, lacks detail, lacks contrast, lacks color variation; wood grain on panel on front of building is too large.
9. basically all architectural geo needs to be chamfered or needs CoronaRoundEdges texmap
10. lighting is flat; left and right side of the building are almost equally lit
11. noise throughout the image; maybe light sources are overbright in the scene and being turned down in the LightMix; use the denoiser.

These are very valuable points for me "no doubt", and you helped me to think on larger circle for my future models - lighting - materials, but i have a question, deos the coronaroundedges texmap do the job? I mean instead of trying to do all the chamfers in revit, which i think its going to take alot of time.
I think i need to work more on light distribution all around the scene.

Why you chose "clay material" as a first step!.

Because it's "neutral" and work at hand is to "enlighten" a vision, which starts with just lighting/shading. Then gradually builds up. Basically it's like when making an illustration, first act is to focus on finding tones & zones creating contrast, defining lines, form, depth...

and do you mean using clay material in the whole objects?!

Yes. And only after when you like what you see, you move on to "surface/materialize" it.

Otherwise, simple mind gets messy... lost.

Got it, thanks, ill try it and will get back to you.

I wouldn't agree that it's mostly a lighting at fault here. While obviously the lighting can be improved, but fundamentaly you can only make it more artistically pleasing, but not more realistic. Actually it's pretty hard to make unrealistic exterior lighting in modern renderers, unless you'll do some stupid things, like start placing lights in the sky.

What i find wrong in your render, is 1. models, 2. materials, 3. texturing, 4. tonemapping. Not in a particular order. I don't have time to go into details, but i'll try to give you some key points aboutneach area.

1. models are too simple and lack of details. All corners are unrealisticly sharp, edges are too perfectly straight, there's zero randomness in placement. Everything's flat, straight and sharp.
2. materials are too simple and unrealistic. It looks like everything except for glass and carpaint, has the same plain roughness value. It looks like you applied the same material to everything and just swapped diffuse and bump maps. Cars looks particularly bad - is that automatic conversion from Vray, or scanline?
3. Where's dirt, weathering, stains, imperfections? The house has been built on conveyor belt 5 seconds ago?
4. the image looks too flat and uninteresting, everything has about the same brightness level, there's nowhere to rest an eye. Nothing catches viewers attention for longer than couple seconds.

Thanks for the points!
But can you give a reference for each point!
I mean i use revit for modeling, how can i make my lines not perfectly straight or randome!.
For the materials, i tried to play with the parameters, but idk i cant get a reasonable output for sorry.
And if you can give me a reference of renders, that can lead me to try fixing my render to not be flat or boring.
Thanks again.

But fundamentally, it's lighting.
First make it look good using only "Clay" material.

Why you chose "clay material" as a first step!.
and do you mean using clay material in the whole objects?!

Well, First of all, I feel like there is something missing out of the materials! It doesn't give me that good realistic feeling! Maybe I have to play with the material parameters for a little bit more, also the lighting and the environment in general! maybe i need to use HDRi to give a more natural sense to the eyes.
But the problem is that I don't know where is the exact problem in such a case! I mean like for the material parameters! what is missing on my materials to be more realisitc!?
Thank you anyway.

Hello guys, hope you are all in good condition, Anyway I am a new corona user, I was using Lumion for the past few years, then when I finished my university I decided to enter the photo-realistic industry, no further talk this is my render, and I feel like it's not what I really wanted to be!
I feel of lack realism!
so if you can point the points that can help me improve my renders and make them more realistic I would be so grateful, thank you.

[Max] I need help! / wavy render!

Hello guys, yesterday i started a render then i had to shut the PC down, so i saved a CXR file to resume my render on the next day, Today i resumed my render and something weird just happened, My render became full of waves all around the image!
and i would like to know the reason!, Thank you.
