Post by: yesharvaishnav on 2019-02-15, 17:41:27: No , i tried both bump and displacement, not working as intended.

Post by: PROH on 2019-02-15, 17:48:06: Well, bump and/displacement should do it. So you might have done it in a "bad" way....?

Otherwise you'll have to model it.

Hope it helps

Post by: yesharvaishnav on 2019-02-15, 17:54:01: what does bad way mean ? i use hi-res black and white image for logo i wish to emboss, i gave 99 to bump but its not showing much of a bump, and displacment too not working proper, i am requesting proper work flow if you guys can help me.

Post by: TomG on 2019-02-15, 17:56:06: For something not working, best to share example renders, plus at very least material set ups in the Node Editor, but even better the scene itself (even if simplified down to non-final geometry like a simple plane, and non-final maps like simple text).

Post by: pokoy on 2019-02-15, 18:36:52: I agree, we don't even know if this is Max or C4d?

Bump at 99 will be quite a bit too much, something *should* happen. Displacement not working could mean that it's not enabled globally. But it really depends what program you use, what's the shader setup, even lighting can matter in this case.

Post by: yesharvaishnav on 2019-02-16, 05:04:00: ok this is what I have achieved so far, please let me know how to improve the quality of displacement and reflection so that it looks super realistic

Post by: sprayer on 2019-02-16, 09:04:55: you may try blur texture in photoshop- box blur for example gives smooth transition but may not work well in some case, or sculpt text and add imperfections at edges etc, and bake zdepth for displacement

Post by: yesharvaishnav on 2019-02-16, 12:22:37: Please try giving bump on the map I sent, it's not working don't know why
Title: Re: how to I achive such metallic embossed effect on label in rendering
Post by: yesharvaishnav on 2019-02-16, 13:10:51: this is what I achieved with displacement.
Title: Re: how to I achive such metallic embossed effect on label in rendering
Post by: pokoy on 2019-02-16, 13:13:25: If the map has a harsh black to white transition, try to blur it, it a smooth gradient will help especially with the bump.
