Hi,

I have been trying to render a simple button battery using a chrome plate appearence (which I expect to be shiny). However, every time I render (on maximum and with a lightsource) it produces a dull material pattern that looks like it has been rendered on a low quality. This occurs with all metals and with some non-metals as well sometimes.

Is there anyway I could fix this problem? And is it even a problem?

I have attached the part if you want to try it out for yourself. Is the problem occuring just for me?

I will also attach a few pics of stuff I have rendered on maximum that don't look quite right.

I am using an AMD Radeon HD 6700M Series VGA.

Also, if possible could you look at my other question I am having problems with: https://forum.solidworks.com/thread/79702

Battery, chrome plate + light source:

Matte aluminium with white high gloss (but it doesnt look very high gloss) plastic:

Hi Rohan,

please see below 2 images i quickly made of your battery. The batterys have identical material settings - but you see different results.

the reason for this is not a bug but rather the fact that the single battery has nothing that it can really reflect...

you havea couple of options to get a refelction:

1) surroundings and studio settings

2) other objects in the model

you will need to try and play with the settings to get your desired results.

If you intend to get more deeply into rendering with PV i suggest a step by step guide - this will also help with your problem in the other post you did.

regards

Helge

btw PV does not mind if you have a Radeon VGA card ;-)

Thanks for your reply! I will try the options you suggested. Also, how did you get a nice 'shiny' render without any other objects. Did you use a studio scene and if so which one did you use? Did you also get the same dull result as I got when there were no other object or surroundings present? And are there any online step by step guides for photoview360 that you recommend?

Thanks once again!

i used a brighter scene on my render. the only difference to your first image is a brighter surrounding. showing a brighter battery - thats it.

I am not sure if there are any online step by step guides available. Maybe sombody else has a couple of ideas.

Another interesting observation that it only occurs with the parts involved in this assembly. It works fine on other parts unrelated to this. Is there anyway I can fix this without completely recreating it. I tried copying and pasting and it didn't make a difference.

Hey Rohan,

Remember chrome objects are like rendering a mirror. They need to reflect something. Chrome "pops" when it has something very high contrast to reflect (whites and blacks). Solidworks has a lot of environments that are very "soft" with gradients etc. these do not make chrome materails "pop" very well. I went online and downloaded a photostudio hdr image which more high contrast. It makes the chrome material look much much better!

environment is too soft and there is nothing to reflect.

Added a .25mm fillet to edge to catch some light, used a more contrasty environment with something to reflect.
