are you ready to render your Sketchup models in Photoshop you've probably seen some amazing examples of the styles and effects you can get when you take an image of a Sketchup model and enhance it using Photoshop spiral tools but wait when it comes to working with Sketchup and Photoshop together there are a few critical mistakes that I see both new and experienced users make that cause them to struggle and can result in subpar renderings I'm Alex Oliver lead instructor at Sketchup school the place where professionals go when they're serious about learning Sketchup and in this video I'll help you avoid those mistakes by covering the key things you need to get right and sketchup first to set yourself up for success when rendering with Photoshop keep watching you already know that Photoshop can be a great tool for transforming your average Sketchup image into anything from stylized concept art to slick more realistic renderings over the years we've taught thousands of professionals the skills they need to take their Sketchup renderings to the next level and we constantly see users who jump into a program like Photoshop only to get completely discouraged after spending a ton of time and not getting the results they were hoping for now if you're a self-taught Sketchup user there's no shortage of tutorials you can find to show you how to recreate a specific effect for a specific kind of project using Photoshop and don't get me wrong the settings you use in Photoshop do matter but what's equally and sometimes even more important is something that's often skipped and that's the Sketchup side of the equation getting things right and Sketchup before you move to Photoshop can play a huge factor in achieving the results you're looking for with your renderings plus there are a number of things you can do in Sketchup that will save you a ton of time and frustration later in Photoshop that's why we've compiled a list of the seven key things you need to get right and Sketchup first before you get to Photoshop one thing real quick before we jump in we're gonna cover a lot of ground in this video so I've gone ahead and put together some notes for you to help you remember everything stick around to the end of the video and I'll let you know how you can get a copy of them okay so what are the 17 things you need to get right in Sketchup first before you get to Photoshop let's start with number one split your Sketchup image into Photoshop layers rendering is done in Photoshop will always consists of anywhere from a few to hundreds of layers stacked one on top of the other to create the final image you can think of each Photoshop layer as a transparent sheet you can have an image that takes up the whole sheet such that you can't see through to the next sheet or you can have a partial image that allows you to see through to something below you can even have layers that use blending effects that change the appearance of the layers below them we'll talk more about Photoshop layers in a moment but for now the key is to start planning ahead and sketchup for the types of layers you'll need in Photoshop let's walk through a quick example so I can show you what I mean if you export a 2d image of your Sketchup model and open it in Photoshop you'll see the whole image is on one layer now what if you just want to adjust the intensity of the shadows without affecting the rest of the image in Photoshop the key to making adjustments like this comes from isolating things onto separate layers so you have more control over them in this case we'd love to have one layer that has the image without the shadows and then a second layer on top of that one that has only the shadows that way we could make adjustments to the shadows layer without affecting the base image by now you may be thinking okay but how do I bring a Sketchup image into Photoshop in layers it starts by creating scenes in Sketchup that will each become their own layer in Photoshop now you're probably used to creating scenes to save different camera views of your Sketchup model but when it comes to prepping for Photoshop you actually want to create scenes in Sketchup that have the same camera view and only change other visual settings you plan to isolate later so in Sketchup you create one scene with everything you want to see but with the shadows turned off and then to create a second scene with only the shadows you turn the shadows back on and use hidden line mode for the faces turn the edges off next you select one of the scenes and export an image then do the same for the other scene once you've exported images from your scenes you need to composite them in Photoshop that's just another way of saying that you need to bring them back in as layers and stack them in the right order and use the right blending mode for each to put your Sketchup image back together to do that you drag the exported images into a new Photoshop file and hit enter to place one on top of the as layers then put the shadows layer on top and set the blending mode to multiply all of the white parts of that layer go away and the black parts blend down to the layer below now you have pretty much the same image from the beginning of our example only this time we can easily adjust only the shadow intensity without affecting the rest of the image once you get the hang of this idea you can set up different scenes in Sketchup to isolate lines profile lines monochrome faces colored faces textured faces shadows and more plus if you use a rendering extension like v-ray for Sketchup you can use this same technique to save render elements that isolate things like reflections and lighting and then you can bring any combination of exported scenes or render elements into Photoshop and composite them together to create a new look in general to get this to work you'll want to experiment using one of four blending modes multiply screen overlay or soft light now while it's too much to try to cover all the possible combinations of scenes render elements and blending modes here today I've added some helpful tips to the notes once you've got your layers and blending modes all set you can try filters adjustments and any of the other tools in Photoshop to create a custom look now this works great when you're dealing with an entire Sketchup image but often you'll want to take your Sketchup model and incorporate it with other imagery in Photoshop that's where the next tip comes in number to export transparency and alpha channels when you need to export an image of your model with the transparent background there are a few things to keep in mind first you need to turn off the sky and ground colors in the background you also need to set your background color to white then when you export be sure to pick PNG and in the options pick transparent background now when you take your image into Photoshop you'll be able to see through to the layer beneath it while we're on the topic of transparency if you're a more seasoned Photoshop user you'll know that there are times where you'll need to create a layer mask to isolate your Sketchup model well you could use Photoshop stoo
Thanks Izetta your participation is very much appreciated
