You could buy Matchstick Man or use the fire for Holiday Nook.
Thank you. Just bought both of them but they really don't give me the effect that I am looking for but thanks anyway.
Are you looking for fire effects? There are some but they're not really shaders.
Sorry then, I though it might be iffy as to where those could suit your purpose. Fire has many different looks to it.
Were you the guy that asked for an actual animated fire a while back? To use fire asa an effect you need to export to Blender, Unity, UE4 and then use the FX that come with those products.
No, that wasn't me.
I have a halo prop for G3 that I want to put on a character's head so it appears like fire is coming from the head. Sort of like what is happening in this link --> https://gcdn.daz3d.com/p/55797/i/muelsfell-storm-of-magic-iray-fx-00-main-daz3d.jpg but with the flame not being on top of the head but circuling the head. I already have the halo that goes around the head, I just need the fire texture to apply to that halo
- Find a fire texture: https://duckduckgo.com/?q=seamless+fire&t=ffab&atb=v170-1&iar=images&iax=images&ia=images
- Change Emissive Colour to white. Turn up the lumen (try x10 or x100), lower the temparature to about 3000.
- Drop your fire map in both Emissive Colour and Cutout Opacity
Those look to be photos of real fire posted worked into that render. They do look good though. I know of no products that good but let me recommend Silent Winter's Fantasy Trapped Vault product: Fantasy Trapped Vault | 3D Models and 3D Software by Daz 3D
It's torch I noticed has a better flame than typical of the other products I've from the DAZ Store that have flame as a part of the product.
I like the 3D flames in The Torch and Construction Kit. The flames can all be loaded individually to arrange as you wish.
You could also try the set I made - https://www.daz3d.com/mmx-fire-and-smoke-for-iray
I purchased your package a while ago but none of those images are shaders. How do I apply your flames to my halo prop?
If you put out another package with shaders in it, I'll buy it. I promise.
How do I conver those to a shader?
Are there shaders for those flamers or just materials.
I looked at the description in your link and it says that it is a material preset and not a shader. Also, I own the package in the image and those are actual flames but they too are material presets and not shaders :(
Every surface needs a shader to get rendered (3DL, Iray, whatever), that's just how it works. A material preset and a shader preset that uses an image file are basically the same. The material preset applies a specific bitmap to a specific geometry so that everything lines up. A shader preset that uses bitmaps doesn't care about geometry, it just tiles the image across the entire surface. How it lines up depends on the UV map of the geometry compared to the bitmap. You can basically take any image and use it to make a shader preset. You can take an image of fire as Hylas described, just drop the image into the appropriate channels on the existing surface settings.
To see how it will line up, look at your halo in UV View to see where in the x-y plane the geometry is mapped. Your fire image will overlay that (dimensions might be different) so you can see what part of the image will be where on the surface. It gets complicated if your geometry doesn't match the image very well, and you have to scale and offset, or make a new image to align with the geometry, like a material preset. Either way, you will be using an image of some sort.
There are procedural shaders that do not use bitmaps, but generate their own effects using mathematical formulas. There is the 3DL shader pwEffect, which has a few flame-type presets, but is a little tricky to customize. There are a few procedural Iray presets in some of the PA shader sets (for fur, or fabric), but not for fire, that I can see.
all of the fire options are dependent on the UV mapping of the target object so you need to use the maps for that object.
hold ctl applying another shader such as MattyManX's and ignore maps in the dialogue popup.
I might be remembering wrong but in DAZ Studio, a material preset equals a shader preset plus images while a shader preset is just the settings without the images so what you want is actually a material preset not a shader preset.
I have that product & the flames are a part of the torch and have a morph to change the shape of the flame so you parent 4 torches to the halo in 12, 3, 6, 9 o'clock positions and apply the morph of the flames to that 2 use one morph and the other two torches use the other morph. You hide the actual torch geometry with cutout opacity. Finally you copy the material settings from any of the 4 flames on the torch and paste to the halo's surface(s).
That's 'general' instructions although you will get flames like a fire while the flames in the image you posted are actually the flames of a petroleum or similar explosion. You need to use GIMP and public domain images to edit & create your own diffuse / emmission textures for the halo and import them into DAZ if you are insistant on a gas explosion as the flame effect.
You are remembering wrong.
A shader preset is a preset which will apply one set of surface settings (values, images, ...) to any surface you have selected.
A material preset is a preset which will affect a specific list of named surfaces / material zonez and apply a set of surface settings (which can be different for each surface) to each of these surfaces.
Fine, thanks, but then a material setting is a superset of shader settings and so the OP's reasoning that a material setting of flames wouldn't include shader settings for flames is wrong, if there is only one flame shader setting in a flame material setting then the effect is going to be the same once applied to the surface as applying the one flame shader setting.
A material can only be applied to the prop that it was designed for. A Shader can be applied to any prop. I have a halo.I would like to apply a flame shader to it. I can not apply a material setting. It will not work. I tried it.
You are correct, but what we are saying is that you can make a shader preset by using a picture of a flame. When you load your halo, it has at least one surface, and it has a shader to render it (DAZ Studio Default, Iray Uber, something). The textures might be blank, they might have something by default. Whatever. Take your picture of fire, and add it to the Diffuse Color (3DL) or Base Color (Iray) channel. You will see something on the surface of the halo if the picture covers the area that coincides with the UV Map. You can tile and/or offset the image to get it to cover the halo the way you want. Then, add the same bitmap to the Emission channel (adjust the color, temperature and luminance), and maybe the Cutout Opacity. Now your halo should be burning brightly.
Wrong! You can copy the materials from the old surface and paste the materials to the new surface. Or you can save the surface as a shader preset and apply to the surface you want and then just choose the images to use on the surface as is or open the dialogue to navigate to a different image and choose that image to use as emmision image or diffuse image or whatnot.
You need to look in the DAZ tutorials at how to use surfaces, material presets, and shader presets so you can use the flexbility in the products you already own.
Do you have a link that explains what your just said?
Sorry, I missed the part where you said you had a prop that you needed a fire shader for. Everything in my set are material presets, not shader presets.
Apon re-reading your post about the halo you made, you could take the beam prop from my set and use the pose controls to turn it into a circle, as seen in this promo - https://gcdn.daz3d.com/p/68271/i/mmx-fire-and-smoke-for-iray-11-daz3d.jpg - scale it down and parent it to G3F's head. For the main promo, I scaled the prop on the Y axis to make the flames appear taller - https://gcdn.daz3d.com/p/68271/i/mmx-fire-and-smoke-for-iray-00-main-daz3d.jpg
Drogo, You are correct about both. What nonesuchoo is suggesting however is that you apply a meterial preset for an item to the intended item and then go to the surface tab and copy it over from the surface its on to the surface you want to use it on. To do that you simply right click the surface that the settings and maps are on and then right click the surface you want it to go to and click paste. Please note, this will NOT alter what surface shader you are using, it simply copies over settings and maps from identically named settings. So if the surface you want to copy to is 3Delight and the one you are copying from is Iray, it will not change the 3DL surface to an Iray surface. Hope this helps.
Mattymanx, I ended up using your product to create the desired effect. Thank you. Thank you for having the product and thank you for telling me how to use it in ways that I did not know about.
