Bump seems much stronger in your C4D version than in 3ds Max. At first i thought that maybe it's because of wrong gamma, but since you're not using normal maps, but rather old fashioned bump maps, that should not be the case. I never used C4d, so i can't possibly know that, but maybe 1.0 bump in 3ds Max does not equal to 100% in C4D? Also, do you use Corona bitmaps in both DCCs?

1.0 bump in 3dsmax = 100 in c4d. so when I look at his fabric material at 0.7 in 3dsmax it should be 70% in c4d, which it appears to be.

I would also like to point out this.

There is no difference in material settings in both applications.

This is the result when I use 255 white light.

I'm sorry it took me this long to respond :(

Apart from obvious difference in bump strength, i think the two renders are fairly similar, isn't? There are some visible difference in shading, so maybe Corona uses different default BRDF models in both DCCs, or maybe your materials are not exactly identical.

1.0 bump in 3dsmax = 100 in c4d. so when I look at his fabric material at 0.7 in 3dsmax it should be 70% in c4d, which it appears to be.

I think it's true for normal maps, but not necessarily so for bump maps. Anyway, someone from the team should definitely know the answer.

Could the authorities be interested in us finding a solution to the problem?

Are you willing to create and post a comparative study scene files for peer review?

I believe some differences may be expected when rendering the same assets in different host apps or render engines. For example, bump value 0.7 could mean something else in Max than in C4D.
I'll check with the devs and will return to you once I have any answers.
Can you tell me which exact version of Corona for Max and C4D you are using? I couldn't find this information in this thread.

Hi guys, I have checked this in both Cinema 4D (my native software) and also 3ds Max with V11 HF1. Both scenes were rendered exactly the same with just an HDRI. Saved and opened in PS, and there is no difference in these renders at all.

Pretty sure the real question here is, Beanz, why do you have a green/yellow cursor?

Because it's better than boring white ;)

Hi,

here is my comparison of the cosmos asset in 3ds max and c4d. I just removed the bump mapping in both, and both renders pixel-to-pixel perfectly the same.

But why? I think it's quite obvious, that apart from mismatched lighting, the biggest difference in OP's examples is in bump mapping. Wouldn't it be better to demonstrate that even with bump mapping Corona can produce identical results in both programs?

Heres one comparing normal/bump.

I use Corona 11 Hotfix 1 versions in both applications.

We made some tests and we are generally getting almost identical results in Corona for 3ds Max and Cinema 4D.
There are some small differences, mostly in the appearance of normal maps. There could be various reasons for this, but the most likely explanation is that the same bump value (for example 0.75) is interpreted differently in 3ds Max and Cinema 4D.
So there may be some tiny differences between the same asset loaded into different host apps, but it does not affect their overall appearance. If needed, you are always welcome to adjust asset materials manually.
