[C4D] I need help! / Re: How to import an obj file

« on: 2020-09-28, 20:49:03 »

Thank you Beanvision and CineMike: Beanvision I got the file from CG Trader. CineMike: Thank you so much for your explanation.  Most of it I understand but some of it (opening the material file with a text editor) is over my head at this point.  Luckily I did contact CGTrader and the designer directly on CGTrader and within about 12 hours he provided a Cinema4D file for me!  Thanks.

[C4D] I need help! / How to import an obj file

« on: 2020-09-28, 10:55:33 »

I am trying to import an object file in Cinema which contains 4 area rugs.  I have two files, an obj file and a material (mtl) file.  Cinema4d will open the obj file, and I get 4 flat rectangles with no finishes on them. How do I get the material file to open as well?  When I click on it Cinema says "file format unknown".  Below is screen shot of the two files I have.  Thank you.  P.S. I know I have opened an obj file in the past of a chair without Cinema4D, and it worked fine but I even forget how to do that.

arjunkumar1108 and davetwo: I agree the Mographplus tutorial package is amazing.  It's very serious stuff.  Not that difficult to understand, though, for the most part.

Marduk: Finally something I think I can help with. (I get a lot of great help here.) I think the strongest thing about Corona is the Sun.  If there is an opportunity to let some sunlight in anywhere, then you can take advantage of how beautiful that alone makes things look.  Try to accomplish much of the lighting that way.  Then I usually add some rectangle lights near ceiling pointing down.  I actually have not decided which is better, spheres or rectangles in terms of realism, still looking into that. I keep sky (and Sun) intensities very minimal.  And yes using an HDRI light material attached to a Cinema sky is nice too, but still need those fake openings.

By the way, I would have been nowhere without pushing convert as you said.  The opacity option check mark came up as part of that.

Here is the jpeg. Thanks again.  That was quick.

Thanks for letting me know about that option.  Wow I pushed that convert button, but then the material looked transparent.  I noticed "opacity" was checked and UNchecked it for some reason, and that worked.  See the new jpeg below with the back mesh showing.  I'll adjust the size of the mesh..  Thank you!

[C4D] I need help! / Trying to render the mesh back on an Aeron Chair

« on: 2020-08-03, 09:04:12 »

I am trying to render an Aeron type office chair, with the mesh material on the back.  I cannot see the mesh/fretted material in the render, the area looks empty, even though I see there is a mesh bitmap (png file?) applied as a material .  If I disable the "alpha channel" it becomes a solid that looks like a mesh but is not transparent.   I am not knowledgeable about Cinema, just using it to import SketchUp models and make the connection with Corona Render.  But it's going well, until I try to render this mesh/fretted material on this chair.  I don't remember a problem with rendering a material like this in Vray for SketchUp or Maxwell for Sketchup, don't remember having to do anything special to deal with it.  But am stuck here with Corona for Cinema4D.

Thank you.   I have attached jpegs below.

[C4D] I need help! / Re: How rotate wood material 90 degrees

« on: 2020-07-14, 09:11:35 »

We need some Corona specific UV controls because the Projector shader currently isn't supported in the IR (unreliable), the Layer + Transform combo is OK but not for bump maps...

If your material projection is set to anything rather than UV-Mapping then you can change it under the "coordinates" tab - once you have the material tag selected that is. Just change the H P B values by 90 degrees, one of them will work :)

You can also place the texture into a C4D layer and then put the Transform effect on top of it. You can use that functionality to rotate the bitmap and it tends to work fine with diffuse textures... Won't work fine with bump maps though.

Thank you Nejc Kilar.  Much later now...I tried this "90 degrees option"and it works great.   Have a little bit more experience and understand what you are saying.

Thank you so much Beanvision, I just tried that and, done!    Thank you as well Nejc, had tried but no success with H P B.

« on: 2020-04-07, 08:10:22 »

I have am using a wood texture jpeg.  It looks pretty nice so far but don't know how to rotate the direction of the wood 90 degrees.  Tried a couple of things I saw on line but either direction didn't actually change or material turned "black."  Admittedly have not studied program as much as I should, am looking for a shortcut asking here.  Thank you.

[C4D] I need help! / Re: Corona lights turning modeling mode all white/black

« on: 2020-03-11, 21:28:11 »

The scene renders as expected.  I inherited the camera with the SketchUp scene I imported.  Don't know if that makes it a Corona camera.  I wanted to inherit the exact same view from SketchUp, not to mention have almost no experience in setting up cameras in Cinema/Corona yet.  But disabling the lights with the selection object, as suggested above, along with disabling the sun, seems to get rid of the black and white while in modeling mode, so I can see what I'm doing.

« on: 2020-03-11, 20:28:04 »

I looked at the lights and saw the "occlude other lights" was actually already checked.  So I UN checked them, and that made the shadow go away.  Thank you for narrowing it down to that option!

I am using Corona lights, placed horizontally a few feet from the ceiling, and they are creating shadows above on the ceiling.  How do I get rid of that??
