Create Explosion in Maya with Fluid

for the first time ...open tab dynamics... as menu tab  choose fluids effects --> create 3D container with emitter click box and rename it to emitter

open your fluid emitter tab set like this

set fluidshape like this

back again to fluid emitter set fluid attributes like this

open fluid shape --> dynamic simulation

scroll to the bottom find content detail

now we set the temperature and fuel scroll to the bottom again set like this

and now set the lighting

open the shading --> opacity

and set again dynamic simulation

and for the shading --> color play aroung in the color... based on real fire

u have explosion 

make a smoke in maya

open tab dynamic and find tab fluid effects ---> Create 3D container with emitter
here is the setting to set the high

setthe fluidshape

and turn off the boundary box

setting for content detail

make fluid in maya

create container with emitter

here is the setting

container base 39
auto resize on
auto resize thres 0.2
density
bouyancy 1.7
diffusion 0.2
display boundary draw none
velocuty swirl = 2.0
turbulance -->strength = 0.06
shading trasparancy - reduce
change the color

play the color

turn on the self shadow

and how to animate smoke in maya use this

and play bouyancy

play with bouyancy

here is the result

How To Render product visualization in Maya

First make your 3d model

and create light --> arealight
here is setting of arealight
intensity = 2.00 open mentalray-->arealight  tab above set high sample 52 ,low samples = 15  , open custom shader -->light sader --> mia_portal_light1 intensity multiplier = 20.0

render setting using image based lighting --> image name fill hdri image
turn on final gather

on the cam setting
open mentalray above --> lens shader --> mia_exposure_simple1 set gamma to 1.500

and for the material using mia_materialx

for the material of base .. or plane
open BRDF
set 0 Degree Reflection  to 0.05
90 DEGREE REFLection to 0.500
brdf curve to 5

and diffuse color set to gamma correction

and you have to set material based on your need

and here result

Make a nice curve in 3d using nurbs object
